NFC North teams added dozens of intriguing young players over the weekend. They filled glaring holes and added to already-established strengths. Some areas remain weak, of course, while other selections created new storylines we hadn't anticipated.

So here's my post-draft plan. We'll use this post to lay out the unfilled holes and new storylines and then circle back over the next days and weeks as needed. I'll also sprinkle in some interesting and/or offbeat stories that emerged from the draft but would have been buried if I had posted them over the weekend.

Issue: The Green Bay Packers continued signaling potential change at left tackle.
Analysis: Coach Mike McCarthy said in March that the team needed better play from its left tackle position, manned last season by Marshall Newhouse. Then the Packers went out and drafted Colorado's David Bakhtiari and Cornell's J.C. Tretter in the fourth round. Bakhtiari has played left and right tackle; Tretter played tackle as well but might project as a guard. Saturday, McCarthy left all options open at the position -- including moving right tackle Bryan Bulaga back to the position he played at Iowa. McCarthy also said he is "really counting" on Derek Sherrod, the Packers' top pick in 2011 who hasn't played since breaking his leg late that season, to compete for the job. Don Barclay, who started four games last season at right tackle (plus another two in the playoffs), is also in the mix. Suddenly, the Packers have six legitimate possibilities to compete for the left and right tackle spots if they want. Moving Bulaga isn't as easy as it sounds, and there is something to be said for leaving him at a position he has excelled at. But it's telling that the Packers are even considering it.

Issue: The Packers drafted 11 players, but none of them were safeties.
Analysis: General manager Ted Thompson said afterwards that he has faith in incumbents M.D. Jennings and Jerron McMillian, who will compete to play alongside Morgan Burnett. We'll see if the Packers feel compelled to kick the tires on a veteran. Among those available are Quintin Mikell, Kerry Rhodes and Gerald Sensabaugh. Historically, the Packers' approach has been to evaluate younger incumbents first before seeking veteran replacements elsewhere.

Issue: None of the Minnesota Vikings' nine draft choices play middle linebacker.
Analysis: We should note that the Vikings used a seventh-round pick on Penn State's Michael Mauti, who has been projected as a middle/inside linebacker by some. But Mauti is recovering from his third career ACL tear and can't be counted on to fill any sort of significant role. Internal candidates include Erin Henderson, the strong-side linebacker whom the Vikings have said could play inside if needed, and 2012 seventh-round pick Audie Cole. The elephant in the room is veteran Brian Urlacher, who was reported at one point this spring to have had conversations with Vikings officials. Urlacher isn't anything close to the profile of the player general manager Rick Spielman typically brings in, but this is an extenuating circumstance. Remember, the Vikings used their nickel defense on 58.9 percent of their snaps last season. Whomever plays middle linebacker for the Vikings could be off the field for two of every five snaps.

Issue: The Vikings used a fifth-round pick to make Jeff Locke the first punter drafted.
Analysis: In the past five years, four punters have been selected with a fifth-round pick or higher. All four became their team's primary punters in their rookie seasons. There is every reason to believe the Vikings plan for Locke to replace veteran Chris Kluwe, perhaps as soon as they get a look at him during their rookie minicamp this summer. I know that Spielman said Locke was brought in "to compete" for the job, but that competition will be short and one-sided. NFL teams don't use draft picks on specialists unless they are certain they want to make a change.

Issue: The Detroit Lions didn't draft an offensive tackle after the departure of both 2012 starters.
Analysis: Riley Reiff, the Lions' top draft choice in 2012, will start at left tackle. The Lions' right tackle could be Jason Fox or Corey Hilliard. That still leaves the Lions thin along the line, especially at right guard if rookie Larry Warford isn't ready to step in right away. Regardless, Lions general manager Martin Mayhew made clear the Lions need to add more depth. "We're really young there so we'll look at some veteran guys there I think over the next few weeks."

Issue: The Lions didn't draft a receiver until the sixth round (Virginia Tech's Corey Fuller), but they almost….
Analysis: According to Ian Rapoport of the NFL Network, the Lions told Michigan's Denard Robinson that they planned to draft him with the No. 136 overall pick. Mayhew had spoken before the draft about Robinson's potential as a "slash" player from the backfield and/or slot receiver position. Robinson, however, was selected at No. 135 by the Jacksonville Jaguars. Eventually the Lions used the No. 166 overall pick to select Notre Dame's Theo Riddick, who is not as explosive as Robinson but is a good receiver out of the backfield in his own right. Ultimately, the Lions finished this draft thin at the traditional receiver position given the injury rehabilitations of Nate Burleson and Ryan Broyles.

Issue: The Chicago Bears did not draft a quarterback, seemingly leaving Josh McCown as the primary backup to Jay Cutler.
Analysis: The Bears figured to be a candidate to draft a quarterback in part because of coach Marc Trestman's expertise in developing them and in part to end the cycle of searching for a veteran backup each year. In the end, the Bears couldn't justify drafting one given their limited number of picks. (They started with five and through trades finished with six.) Said general manager Phil Emery: "Things would have to line up perfect to take a quarterback with five picks." McCown was relatively impressive during a two-start stint to end the 2011 season, but overall he has played in a total of six games over the past five seasons. I wouldn't call this the Bears' most pressing need, and the Bears signaled as much with their draft results.

Issue: The Bears feel better about their tight end situation than most draft pundits.
Analysis: Many draft analysts thought the Bears would draft Notre Dame tight end Tyler Eifert if they had a chance, but they passed him up Thursday night in favor of offensive lineman Kyle Long. Eifert went one pick later to the Cincinnati Bengals. It's true that Eifert would have been a luxury pick given the free-agent acquisition of tight end Martellus Bennett, but in the larger sense he would have been another weapon for quarterback Jay Cutler's make-or-break season.
