And by "interesting" I dont mean "OMGZ, The Bills gotta sign him!1!1!!!1!" I just mean they are at least known players. Some, as you'll see, even played some seasons in Buffalo. Here are some of the cuts so far...
Courtney Watson LB (Texans)
Antowain Smith RB (Texans)
David Loverne OL (Texans)
Sam Cowart LB (Texans)
Eric Warfield CB (Patriots)
Eddie Freeman DE (Patriots)
Chad Brown LB (Patriots)
Monty Beisel LB (Patriots)
Matthew Rice DE (Rams)
Charles Rogers WR (Lions...according to ESPNews soon to be cut)
From what I can see using KFFL, only the Texans, Patriots, Rams and Bears have swung the axe this early.
