We'll be going to a different schedule the next few weeks in which we'll break up the questions. Some will appear on Tuesdays and others will appear on the traditional Friday slot.
Here are some of the best ones I've received over the past several days.
Andrew from Clemson, S.C., writes: Tim, with Kansas getting so much off-season hype to win the Big 12 North, do you think some are underestimating the loss of the members of their offensive line and linebackers from last season? I know here in Clemson after we saw what happens with a young offensive line and linebacker corps.
Tim Griffin: You raise a very good point. That rebuilding is the major reason why I'm a little hesitant to pick the Jayhawks for the North title. Even with Todd Reesing, Dezmon Briscoe, Kerry Meier, Jake Sharp and all the rest, the play of the Kansas defense will be critical.
I'm thinking the Jayhawks will miss Joe Mortensen, James Holt and Mike Rivera. And the loss of guards Chet Hartley and Adrian Mayes and center Ryan Cantrell could be even more of a challenge, considering they anchored of the Jayhawks' line.
I'm also a little leery about the Jayhawks' cross-division opponents. Drawing Texas, Oklahoma and Texas Tech will mean the Jayhawks will be playing three of the four likely toughest South opponents.
It won't be easy. And that's why I think the North will be an interesting race.
John from Austin writes: Tim, I wrote you a couple of weeks ago how Texas doesn't seem to be in the running for guys who like to make the dramatic "hat" choices on ESPN (to announce where they are committing). But I was thinking about the 19 2010 commitments the school has already attracted. Most of them show up, maybe we are cradle robbers instead of the "hat guys?"
Tim Griffin: Or maybe Mack Brown and his staff feel like they can circumvent the whole "hat process" by picking his recruiting targets early and signing them. It looks like he's done a pretty good job so far -- at least this spring anyway.
Abe Clark from Durham, N.C., writes: I'm curious if you misread a question in your last chat? You ranked the best teams in the Big 12 last year as Texas, Oklahoma, Oklahoma State and Nebraska. Did you think the ranking was for the upcoming season? Where's the love for one of the best Texas Tech teams in history?
Also, I love your blog and your insights.
Tim Griffin: Sorry about that. I did think the question was for the upcoming season. Some of those questions in our chats are a little like the lightning round from "Password," for some of my more television-savvy readers. We try to crank as many out as we can. I'll try to read them a little more clearly next time.
As far as last season, here would be my final Big 12 rankings: Texas, Oklahoma, Texas Tech, Oklahoma State, Missouri, Nebraska, Kansas, Colorado, Kansas State, Baylor, Texas A&M and Iowa State.
And also I agree that arguably, the last Texas Tech team was the best in the history of the school. The Red Raiders' 10-0 start and No. 2 ranking late last season also made it one of the most memorable seasons as well -- both for Texas Tech fans and Mike Leach's pocketbook with the new contract extension.
Steve from Roanoke, Va., writes: Just wondering what you think about Oklahoma's defense. Will they be much better than last season?
Tim Griffin: I do think the Sooners' defensive unit will be a backbone for the team. The Sooners have nine starters back and some key producers like Gerald McCoy, Travis Lewis, Frank Alexander, Dom Franks, Keenan Clayton, Auston English and Jeremy Beal. The defense will be particularly important in the Big 12 where offenses will again be so predominant. The team with the best defense might end up as the best team, because I think many teams will have big offensive units.
I think the biggest key for the Sooners will be the play of their new safeties after starters Nic Harris and Lendy Holmes both departed. The play of Quinton Carter and Sam Proctor will be critical as the projected starters. And also keep an eye open for a contribution from rangy redshirt freshman Joseph Ibiloye, who has turned heads in winter workouts.
John S. from Williamsport, Pa., writes: Who do you believe assumes power in the North? Missouri loses Chase Daniel, Jeremy Maclin and all of the guys on defense. With the staff changes in Columbia, it looks like they will be taking a step back. My guess is Nebraska or Kansas. Who do you think?
Tim Griffin: I'm thinking that Nebraska would be my slight favorite over Kansas, mainly because of the Cornhuskers' cross-division schedule compared to Kansas'. But it wouldn't surprise me if Colorado creeps into contention and I still think Missouri and Kansas State will be representative teams that have their moments, too. I give Nebraska a slight edge, but I want to take a close look at their quarterbacks this spring before I anoint the team heading into the summer.
Jason Peters from Oklahoma City writes: Tim, what would you consider are the greatest teams in Big 12 history? And are my Sooners included on the list?
Tim Griffin: Most definitely. They aren't the best team, but are among several of the best. Here's how I would rank them.
1. 2005 Texas
2. 2000 Oklahoma
3. 1997 Nebraska
4. 2004 Oklahoma (Maybe higher if Mike Stoops coached them all season)
5. 1999 Nebraska
Keep the letters and e-mails coming and I'll try to answer a representative sampling of them later this week. Thanks again for writing.
