I just found this site, and I'm surprised it hasn't been mentioned before:
http://asp.usatoday.com/sports/footb...s/default.aspx
It has key cap information for all players, as well as general information for each team.
Since the CBA may be coming to an end (am I the first to notice this, too

?), this may be helpful in making sense of the ensuing FA free-for-all.
