we need to be doing the same thing with DD, CWeb and KP
Don't know about that. It's a nice 'tough love' concept that is kind of awesome in a vacuum, but you have to think of how it will affect the rest of the locker room.
It's a little different situation for Nnamdi and the guys you've mentioned. You're talking about guys who have only played with the Giants vs a hired gun who has failed to meet expectations. I think the ultimatum works with Nnamdi because the eagles paid for the best CB in the league (tied with Revis at the time of the signing) and he's been far from that.
Take a cut or BE cut....words no player ever wants to hear.
The Eagles should keep Nnamdi at all costs. ;)
