‘Money is a big part of why there are so many good free agents still available. There’s less of it to go around, and in the Bills’ case there’s only about $3 million to work with, according to Spotrac.com.

Pittsburgh saved $8.25 million and that’s the number that Nelson is likely to command once he finally decides on a team.’
