Closer look at Bills' highest cap hits

With the free-agent signing period a little more than a month away, teams continue to evaluate their standing under next season's salary cap.

While the NFL's exact salary cap has yet to be determined, the Buffalo Bills are expected to be in the middle-of-the-pack as far as cap room; they will have some money to spend, but won't be able to break the bank.

In that light, here is a look at Bills' players with the highest cap hits for next season:

DE Mario Williams -- $18,400,000

WR Stevie Johnson -- $8,500,000

DT Marcell Dareus -- $6,493,232

DT Kyle Williams -- $5,800,000

C Eric Wood -- $5,300,000

RB C.J. Spiller -- $4,166,666

CB Leodis McKelvin -- $4,150,000

RB Fred Jackson -- $3,643,750

QB Kevin Kolb -- $3,600,000

OT Erik Pears -- $3,450,000

Where do the Bills rank against the NFL average?

Their top 10 cap hits total $63,503,648, which is 61.8 percent of their team cap hit. That is 5.6 percent less than the NFL average, meaning the Bills are less top-heavy than the norm.

Meanwhile, their top 25 cap hits total $89,487,978, which is 87.1 percent of their team cap hit. That is 2.6 percent less than the NFL average.

Of the most expensive players under contract for next season, the player that is least likely to play with that cap hit is Kolb. After suffering a season-ending concussion last August, Kolb's playing future was in jeopardy. With EJ Manuel already named the starter for next season, it's likely that the Bills will either restructure Kolb's contract or release him by March.
