I think it matters because Young is #10, really, and not the most intelligent QB playing.

Plus you add the Titans #27 rank OL, now you have a hurried offense.

Young might just wing it to Moss without thinking, interceptions. Young isnt even close to Brady. At least Brady looks, and makes an educated assessment on coverage.
Moss is used to being a diversion on N.E. and not the #1 receiver, Welker is the #1 ball catcher. Moss will be the #1 receiver on the Titans. I think it will take him a few games to accept that and change his hunger.
I might be wrong, but my bet is no change on the Titans, and maybe a few more Ints because of the Moss move, or wasted 3rd down passes. Until week #11 where Vince and Moss can get on the same page.
