1. This locker room doesn't have Tedy Bruschi, Lawyer Milloy, Ty Law, Richard Seymour, Willie McGinest to police the locker room.
2. All three of those guys were joining a team with Super Bowl cache. This team is far from that.
3. Harrison was a hard ass that no one wanted to play with, the opposite of Pickens.
4. Moss was looking to prove he could do it still, and he was already a HoF player. Pickens has talent, but ain't no Randy Moss.
Somewhere between Bill Belichick eschewing knuckleheads and Pickens there's a middle ground. You want to put him on a the 2003-2004 team and let those guys mold him into a Patriot? Fine. Now? Absolutely not.
