Normal rules do not apply.
Agreed, but he seems to have a ton of respect for BB, so the chances of something like what happened in TEN and MIN happening are slim. Still a big risk, though, given his personality and decline in on-field production which is why I'm on the fence. But I think you need to seriously consider it, especially if he comes aboard on the cheap.
To put it in a different light, there are a lot of people who think that getting an outside threat at WR is a big offseason need for the Pats, given what happened against the Jets (I don't hold this view). If one holds this view, then the answers include (a) signing a FA or (b) trading for one using existing draft picks. The (b) is certainly a possibility given the Pats haul of picks. But if you can accomplish the goal with (a), and cheaply (i.e.: by signing Randy Moss), then that means the Pats can still spend draft picks on other positions of need, or (preferably) to draft BPA.
This of course implies one thinks Moss still has what it takes. As noted above, this is questionable.
