You hear about players signing with another team late in their careers "for the love of the game". (Seems like that just happened recently, hmmm, can't seem to remember now...

) I would think that for players like Seau and Brown, after experiencing the Pats approach to playing team football, "the game" takes on a whole new meaning, and it would have to be pretty darn hard to love another team's way of doing it. I'm sure Troy came to that.
A bona fide majorly contributing 3-way player (Off., Def., ST), has the league seen anyone else his equal in that regards in the past 30 years? About the closest to that I can think of would be Deion Sanders, but I wouldn't call him a regular offensive contributor, and never a major factor on offense.
Definitely one the greatest Patriots...and
team football players...ever. Perhaps his comparative stats may not support that claim, but he is the true epitome of a team football player.
