What's more, Belichick and others sat face-to-face with him and very bluntly told him the rules before the trade that this would be the case, and he said he'd be on board with that and offered to slash his salary for the opportunity.
So the upshot is that the Pats used their 1st round pick to get SF's 1st round pick next year and a throw-in 4th rounder that became Moss.
This Pats fan would be lying if I said I'm totally comfortable to see a knucklehead added to the mix. But...
The price was essentially nothing, the talent is hall-of-fame caliber, and the ability to imediately cut him should things not work out makes it an absolute steal.
