Some teams have multiple holes to fill. These are each team’s weakest link, in my opinion.
Quarterback: Bills, Buccaneers, Jets
Tampa Bay is going to keep Jameis Winston in the same state with the first overall pick in the draft. Buffalo may very well stand pat with a high draft pick in E.J. Manuel and veteran Matt Cassel, but even then, this team is pretty close to making noise. NY might roll with a high draft pick of their own in Geno Smith, and veteran Ryan Fitzpatrick. Like the Bills, the Jets aren’t too far off as one would think. Also, if Marcus Mariota slides, they could make a play for him.
Running Back: Chargers, Cowboys, Patriots
The Bolts and Boys saw their starting running backs sign with the Eagles. Dallas has the luxury of a good O-line, and just signed Darren McFadden. However, a playoff team has fewer holes to fill and, well, RB remains the weakest link. San Diego is used to life without Ryan Mathews. Although the O-line isn’t that strong, they don’t have a starting caliber running back on the roster right now. New England shuffles faces as much as any team does as far as roster movement goes. That goes for the backfield too, on a week-to-week basis.
Wide Receiver: Bengals, Chiefs, Raiders, Ravens
Cincy has seen A.J. Green play through injuries, Marvin Jones miss all of last season, Mohamed Sanu stepped up here and there, but they’re a complete team on paper otherwise. KC might not place much emphasis on wide receivers or anything like that, but they’re pretty much set everywhere else to stick around the playoff hunt.
Tight End: Browns
Consider that the Browns drafted a QB in the first round last year and signed one of the better backup QBs this offseason. They have to find someone to replace Jordan Cameron, and appear in more games than he did. They really don’t have any options for any QB to throw to at tight end anymore.
Offensive Line: Rams, Seahawks, Texans, Titans
These are some of the lines that I perceive, as ranking in the lower third of the NFL. Nick Foles had a great half season run when he got time to chuck the ball downfield. Houston and Tennessee are apparently rolling with the QBS on their roster, so they need to protect them. Seattle simply isn’t missing much.
Defensive Line: Bears, Broncos, Packers, Saints
Chicago is transitioning to a 3-4 defense and needs to find their pieces up front. Denver and Green Bay may have speed on the other two levels, but all will be for not if they can’t hold their own in the trenches. New Orleans should be tired of people marching in.
Linebacker: 49ers, Cardinals
Surprisingly, San Francisco lost Pat Willis and Chris Borland to retirement. Arizona needs to beef up the second layer of defense.
Defensive Back: Colts, Dolphins, Eagles, Falcons, Giants, Jaguars, Lions, Panthers, Redskins, Steelers, Vikings
This appears to be the focus for most teams this offseason. A good secondary is hard to put together, and all of these teams could benefit from more than one addition. You could probably add more teams to the mix for help in the secondary, it’s just that these teams have their most glaring hole(s) on the back-end in a passing league.
