LOL.....so the pats got nothing in exchange....
Based on the facts present we can conclude two things:
A) The Patriots are stupid
B) The Patriots saw Randy Moss as such a distraction, that they would rather get rid of him now, even if there was no increased value.
C) The Vikings are stupid because Moss is washed up.
Even though the Pats have fucked things up in the past few years, I don't know many people that would call the organization stupid. Other adjectives come to mind, but not stupid.
As for B, we know Randy wanted an extension. We know the Pats weren't going to give it to him. Maybe he really started to be a locker room problem. When Moss first came to the team, there were strong personalities to keep him in check. Now he's supposedly one of the leaders.
As for C, the Vikings aren't stupid either. Moss still clearly has value (one-handed TD against Revis is one of the best recent examples), but it is also obvious that he is slowing down, isn't a great blocker, and sometimes takes plays off. The Vikes are desperate for an offensive weapon, so they can probably tolerate any Randy-Antics... the Pats have an explosive offense with or without Moss, so they don't have to put up with his crap.
As much as Bill's shiny reputation has been tarnished lately, he isn't stupid. I think it's likely that some sort of locker rift opened up that was irreparable, similar to the Nomar situation with the Red Sox in '04.
