In light of the roster cuts I was trying to think of teams who made a mistake of not re-signing a specific player and honestly the one that came to mind first is Adam Vinatieri.
I know what you're thinking; but this guy wasn't even asking for THAT much and when you throw in the fact that he is a team legend and argueably the most clutch kicker of all-time it seems mind boggling...
not only that, but you let him goto the Colts where a year before a K basically ended their season. The Patriots essentially gave the SB to the Colts last year...that Ravens game was all Vinatieri...the man is clutch and you shouldn't let clutch players go.
That's the biggest one I can think of, any1 got any other ones?
I know some people will say Farrior but the guy wasn't even that good on the Jets soo I'm not a fan of that one but will respect it never-the less.
