If there's one thing that separated the Green Bay Packers from the Minnesota Vikings — more than Adrian Peterson, perhaps — it's the offensive lines.
While there weren't any weak links on the Packers' line, there wasn't a dominant blocker who could ensure a third-and-1 conversion. In contrast, the Vikings have left tackle Bryant McKinnie, left guard Steve Hutchinson and center Matt Birk to run behind.
An even bigger issue is at offensive tackle, where Chad Clifton and Mark Tauscher are getting up there in years. Both will be entering their 10th seasons. Clifton battled through a variety of aches and pains, especially with his knees, and Tauscher will be coming off of reconstructive surgery to his left knee.
Tauscher is a free agent, and between that and the knee, his status is in limbo. Outside of left guard Daryn Colledge, the Packers don't have ready-to-go replacements for either, so tackle might be a target in the draft or free agency.
Speaking of free agents, the Vikings' Birk will be available on Feb. 27. Sources say he and coach Brad Childress don't see eye-to-eye, and Birk will be free to shop his services. He's one of several quality centers who will be on the market.
Here is a look at the NFC North's offensive lines.
Starters — LT Chad Clifton, LG Daryn Colledge, C Scott Wells, RG Jason Spitz, RT Tony Moll. Backups — G Josh Sitton, G Allen Barbre, T Breno Giacomini, G Nevin McCaskill. Injured reserve — T Mark Tauscher.
The return of Tauscher, a starter at right tackle since his rookie year in 2000, is up in the air. His value as an impending unrestricted free agent diminished when he suffered a torn ACL in his left knee with three weeks left in the season. Tauscher probably won't be ready for the start of training camp, wherever he winds up, after undergoing surgery this month. So, the Packers could be ready to move on with his spot, and doing the same with the similarly aging and wounded Clifton on the left side also is a possibility. Fortunately for Green Bay, many of their young linemen are well-versed in playing different positions. Moving Colledge to one of the tackle spots is a good possibility. He came on at the end of the season but isn't a polished inside player after primarily being the starter at left guard the last three seasons. The shakeup could further continue between the tackles as the offseason progresses. Sitton, who started at right guard in the season finale, is ready for a full-time shot after his possible starting assignment as a rookie at the outset of the season was derailed by a preseason knee injury. Spitz, the regular starter at right guard, is better suited to play center, which could bump the dependable, but injury-prone Wells from the lineup. Barbre has been billed as starting material, but it hasn't happened, though the spot at left guard could be his for the taking. Depending on what happens with the trio of Tauscher, Clifton and Colledge, Giacomini is a candidate to start at right tackle after a year of development as a rookie.
This group performed adequately considering its lack of talent. St. Clair served as the place holder for 2008 first-round pick Williams, whose development was derailed by a back injury on the second day of training camp that required surgery and kept him off the practice field the first half of the season. He should be the starter at LT in '09. Beekman played well enough to unseat perennial tease Metcalf, who has been given a job several times but has always played himself out of it. Kreutz may no longer be a Pro Bowl player, but he's still above average and a coach on the field. Garza is solid enough, but an upgrade wouldn't be difficult to find. Tait will be 34 next season, and he's not getting any better at this stage of his career. Buenning isn't what any team is looking for in a starter or even someone who has to play significant minutes.
The Lions started eight different combinations, thanks to injuries and ineptitude, which hurt the continuity and consistency. Backus played well against some top pass rushers but also took some killer penalties. Mulitalo lost his job to Cook at times. Raiola brought passion and seemed to play OK, but the Lions actually started to run better when he was out with a broken hand and McCollum was playing. Peterman wasn't exactly dominant. Cherilus struggled to beat out Foster early in the season. While he showed potential, he made too many mistakes.
This group deserves credit for helping Peterson win the NFL rushing title, but they also gave up 43 sacks. While Birk, Herrera and Hutchinson did not miss a start, the same couldn't be said for the tackles. McKinnie, who was arrested last offseason after a brawl outside a Miami nightclub, was suspended for the first four games for violating the NFL's personal conduct policy. When he did return, it took him some time to get back into the swing of things. Cook, meanwhile, started the first 10 games but was benched in favor of Artis Hicks after making a variety of mental and physical mistakes. Cook did not remain on the sideline very long because Hicks aggravated a triceps injury he had suffered in the regular-season opener at Green Bay while playing in place of McKinnie. It's believed that right tackle will be a primary focus of the Vikings this offseason as they look to upgrade. But this does not mean Cook's days on the roster are numbered. With Birk set to become a free agent after 11 seasons in Minnesota, Cook could get an opportunity to shift back to his college position of center. Sullivan also could get a look at that spot in training camp if Birk departs. Hutchinson, a perennial Pro Bowl player, and Herrera are solid at the guard spots, although the latter still has plenty of room to improve. Hicks is a valuable backup with the ability to play either tackle or guard position. Johnson, the lone remaining member of the Vikings' 2005 draft class, could find himself elsewhere next season. The Vikings liked Radovich enough that they kept him on injured reserve this season after the undrafted free agent from Southern Cal suffered a shoulder injury.
