I read 6-8 weeks for Edelman over on Sosh (by a guy who broke the news from an 'unnamed source' yesterday at 4pm, well before any news source even mentioend there may be an issue)
I doubt Tate is ready to do much in the way of WR, having not practiced at all (and we see the importance of being on the same page as Brady). I would assume that will be either Aiken or Nunn (although I doubt Nunn).
I wouldnt be surprised if they had Faulk return punts...it seems like you really need to earn BB's trust back there, and while Tate is probably more explosive and a greater threat to bring it to the endzone, I would assume BB will give it to the guy who he has faith wont turn it over or make bad decisions on when to let one go and when to try a return.
