With cut day now behind us, all 32 NFL teams have settled on their initial 53-man rosters for the coming season. And while most clubs had little trouble purging their rosters, the cuts - combined with a lack of initial depth - have left a handful of teams short at key offensive positions.
Here are three units in need of a few extra skill players:
Buffalo Bills quarterbacks
With E.J. Manuel expected to miss the opener with a left knee injury and Kevin Kolb's career possibly over due to concussion issues, undrafted rookie Jeff Tuel is slated to start under center in the Bills' season opener against the New England Patriots. Manuel is considered Buffalo's QB of the future, but it might not hurt to find an experienced backup to replace Kolb.
Free-agent options: Vince Young, John Skelton, Tim Tebow
Baltimore Ravens running backs
It isn't that the Ravens will struggle in the backfield - Ray Rice is one of the most talented running backs in the league, and Bernard Pierce is a capable backup. But here's the problem: As of Sunday's 53-man roster deadline, Rice and Pierce are the only running backs on the Baltimore roster. Expect a depth addition in the coming days.
Free-agent options: Michael Turner, Lance Ball, Jonathan Dwyer
Detroit Lions receivers
When you boast the league's most explosive receiver in Calvin Johnson, it's hard to consider the position a weak spot. But with the ordinary Nate Burleson and project Ryan Broyles behind him, Detroit could stand to benefit from having another elite pass-catcher - particularly if Johnson struggles or suffers an injury.
Free-agent options: Robert Meachem, Tavarres King, Austin Collie
