Thanks to everybody who answered my question with Seymour and Branch, I apparently never thought of them?
Matt Cassel is a pretty decent shout, although the Chiefs also got good value out of that trade, considering they got Cassel and Vrabel for a 2nd round pick.
I just don't get this idea that the Pats/Belichick are masters of getting more than fair value from the players they trade away.
And picking up bargains like Moss/Welker/Blount etc (something we're also very good at) is the opposite of what we're talking about, which is getting rid of players for a premium that is more than their value.
Trades like Herschel Walker, Rick Mirer, Carson Palmer (to the Raiders), RGIII (essentially), Roy Williams (to the Cowboys)... and Deion Branch are fleecings. But the last one is the only time I can think of the Pats getting the better of someone when trading a player away, and in reality we have to give Ruskell credit for that, not Belichick. I just don't see where they get their trading reputation...
