The final tally for my recently completed 12-team training camp tour was more than 2,600 miles of driving and more than 5,000 of flying. Just so you know, you have more flexibility in the Midwest and East if you drive.
Thunderstorms delay planes, but not cars. And no, I didn't have a driver. I only saw the Mort Bus. When you throw in minicamps and OTAs, I've seen 17 teams and will see Oakland, San Francisco, San Diego and Denver this week.
In the NFC, the Minnesota Vikings were the best team I saw. You can't run on them, and they are difficult to pass against because of their pass rush. I'm not saying the Vikings are the favorites to win the NFC; I didn't get the pleasure of seeing the four NFC East teams in person.
Figure the NFC North to be a wild battle. The Vikings have the best starting lineup except for the quarterbacks. The Green Bay Packers are better than you might think, thanks to their move to the 3-4 defense. Aaron Rodgers performed like a Pro Bowler with his two touchdown drives against the Cleveland Browns in the preseason opener. And don't worry about Jay Cutler's so-so performance in his Chicago Bears debut. I'm more concerned about the Bears' leaky defense than Cutler and the Bears' passing offense.
The good news for the Seattle Seahawks is that they can match up pretty well against a talented outfit such as the San Diego Chargers, as the Seahawks showed in San Diego this past weekend. The bad news for the Seahawks is that their NFC West rival Arizona Cardinals appear to be better on defense. Cardinals QB Kurt Warner is just fine after his hip surgery.
The Atlanta Falcons have a slight edge over the New Orleans Saints and the Carolina Panthers from what I've seen so far. Falcons head coach Mike Smith still has a lot to work on with a defense that changed five starters.
In the AFC, the Pittsburgh Steelers are the best of the eight teams in that conference I've seen. Don't worry, New England Patriots fans -- I still have the Pats seeded second in the AFC behind the Steelers. Despite their bad performance against the Packers, the Browns still can be a team that plays close to .500 because of the schedule. The Cincinnati Bengals will be in the seven-to-eight-win range, too.
In the AFC East, the New York Jets are closer to the Buffalo Bills than I suspected because of their defense and rookie quarterback Mark Sanchez, who will win the starting job. I'm a little concerned about the Bills' offensive line.
Let's go to the mailbag.
From the inbox
Q: After reading that story about Michael Crabtree the other day, it made me sick to my stomach. During the draft I was hoping the Eagles would trade up to get him because I feel we needed that hard-nosed receiver. Now I'm glad we didn't waste our time. Where does he get off demanding all this money when he hasn't proven anything when it comes to the NFL? Do you think that Mr. Goodell should look into standardizing rookie salaries either across the board or make the top-10 picks get a certain salary and then a standard contract after that?
From Ryan in Philadelphia
A: Every year there are going to be draft holdouts; as long as the current system remains, at least. San Francisco 49ers selection Crabtree, a receiver out of Texas Tech, felt he was better than the 10th pick in the 2009 draft. The Oakland Raiders' signing of receiver Darrius Heyward-Bey, the No. 7 overall pick, raised the cost of the draft choices in the top 10. With the likelihood that the Buffalo Bills will sign Aaron Maybin this week, Crabtree and Andre Smith of the Cincinnati Bengals will be the last two draft choices out. Once Maybin gets done, it should speed up talks with the 49ers and Crabtree. I predict Smith will be the last first-rounder holding out of the camp.
Q: The one-year "Brett Favre experiment" for the Jets seemed to be a success in the eyes of many Jets fans, but was it really? His old body caught up to him by the end of the season (making just another NYJ disappointment) and the Jets were caught up in seeking after another QB this offseason. I am not complaining of a waste at a first-round pick for Mark Sanchez this season, but do you think the team could make a smooth transition from virtually polar-opposite QBs? If not this year, how long?
From Matt in Morristown, N.J.
A: You don't win in this league without quarterbacks. They gambled on Favre and got off to an 8-3 start, which was great. I don't know if they could have gotten a Mark Sanchez last year. Sure, it was embarrassing to lose a playoff spot to Chad Pennington after he went to the Miami Dolphins, but the Jets decided it was time to move on from Pennington. I would have stayed with Pennington. The Jets might have won nine games with the easy 2008 schedule, but Pennington probably wouldn't had been the starter given where the Jets were going.
Q: Do you think that with the Packers' personnel on defense that they have a shot at making a smooth transition from a 4-3 to a 3-4 and remaining consistent every week? If so, can the Packers be a more aggressive team with this change?
From Mike in Ladysmith, Wis.
A: I'd give it a B grade. Ryan Pickett looks good at the nose tackle position. I think there are enough defensive ends to make the 3-4 work. The cornerbacks -- Al Harris and Charles Woodson -- have bought into the new system. I just think there will be a two-year transition at linebacker. Aaron Kampman got off to a good start in the first preseason game against the Browns at outside linebacker. Injuries have slowed the other outside linebacker spot, but Clay Matthews should be fine there. The problem could be on the inside. There isn't a run-stopper. On the positive side, I think this could be one of the better 3-4 transitions.
Q: If Matt Schaub can't stay healthy, or doesn't perform well this season, is it time to start shopping for a new signal-caller in Houston? Small, extremely biased side note: I still think letting David Carr go was a significant mistake for this franchise. Of course, starting him from Day 1 was a mistake as well.
From Mike in Toledo, Ohio
A: If the Texans don't get over the hump and have a winning record, there could be a lot of changes. Everyone is on the hot seat. I think Gary Kubiak and Rick Smith have done a decent job of rebuilding the roster, particularly on defense. Schaub is an efficient, accurate quarterback who should be able to get this team to nine wins if he stays healthy. Owner Bob McNair is patient, but it's time for this team to step up. They had to move away from David Carr because he was beat up physically and mentally. Yes, I agree they shouldn't have rushed him into the starting job.
Q:What are your thoughts on the battle going on between [Indianapolis Colts running backs] Donald Brown and Joseph Addai? I can't understand why they are kicking Addai to the curb. The guy had an outstanding rookie campaign, has playoff experience, and has been plagued by injuries. This isn't to say that Brown doesn't have a huge upside, but why ditch the veteran? Is Brown going to jump Addai on the depth chart?
From Matt in Poway, Calif.
A: It's not much of a battle this year. Joseph Addai is the starter, but Donald Brown looks great on some of the inside runs. They should be a great 1-2 punch as long as the offensive line can stay healthy and grow together. Brown is noticeable when you watch him in practice. He's got an explosive first couple of steps and is hard to stop on first contact. Addai is the elusive runner and better on the stretch plays, which set up play-action passes for Peyton Manning. Next year will be more of a battle for playing time, but I think Brown could get five to 10 carries a game this season.
From Karyn in Paramus, N.J.
A: I like Jerome Harrison, but I don't see him as being the No. 1 back in Cleveland. He's a perfect No. 2 back on any roster because he's a good runner and seems to do everything well. Eric Mangini wants to install a power-oriented run game. Jamal Lewis has had a lot of carries during his career, but he gets one more season as the Browns' feature back. My guess is that the Browns will be looking for a back next season, which won't allow Harrison to advance much.
Q: If a QB completes a 5-yard pass in which the RB runs for another 75 yards, the QB is credited with an 80-yard completion. Why is that? The QB did absolutely nothing for the majority of the play, so why should he get statistical consideration for it? Seems to me the QB should get a 5-yard-pass credit and the RB a 75-yard-run/reception credit. Instead the QB gets an 80-yard-pass voucher and the RB does as well, totaling 160 yards for a single 80-yard play.
From Alan in Lubbock, Texas
A: There are stats organizations that keep track of run-after-catch, but those specifics aren't identified in the official NFL stats. The NFL isn't like baseball in many of its stats breakdowns, but it is getting better. Sure, it's unfair, but look what YAC (Yards After Catch) did for Matt Cassel. It made him one of the highest-paid quarterbacks in the league. Cassel threw short lobs to Randy Moss, Wes Welker and Kevin Faulk and had a near-Pro Bowl season for an 11-win Patriots team last year.
Q: I'm curious about your opinion on the impact of the Baltimore Ravens losing Jason Brown. He was a large center/mauler who could handle the large NTs of the AFC North. How do you see veteran Matt Birk handling Shaun Rogers, Casey Hampton, etc.?
From Ned in Baltimore
A: To keep an offensive line together, you sometimes have to make sacrifices. The Ravens couldn't afford -- under the salary cap -- to pay $7 million a year for a center. Jason Brown is perfect for the AFC North. But Ozzie Newsome has done a great job over the past three years rebuilding the line. He's made it bigger, stronger and younger. Losing Brown was huge. Matt Birk is a nice replacement for a year or two until Ozzie finds the next Jason Brown. In this case, the loss of Brown was a tribute to how well the Ravens did in finding offensive line talent.
Q: Do you think Green Bay was wise taking B.J. Raji over Brian Orakpo in the 2009 draft? Orakpo is a DE/LB and I hear that they are just going to move Raji to the DE, even though he is a DT. Do you think that Orakpo would have been the smarter choice looking at what position needed to be filled?
From Chris in Gahanna, Ohio
A: What a great question. From what I see of Orakpo, he has a chance to be a 10-sack star. Players like him are hard to find. But if you are switching to the 3-4, you have to find big defensive linemen. Raji is good enough to be a 3-4 end, but if needed, he can be Ryan Pickett's replacement at nose tackle in the next couple of years. The fact that the Packers drafted Clay Matthews covered the outside linebacker question, but, wow, I'm thinking Orakpo could be a star.
