If bill wants sanders it should be an indication that the patriots
A. Like him alot
and
B. Don't think they can find something better in the draft.
There two biggest positions we've had trouble with for years have been CB and WR, and when you think about it, they are very similar positions with a 'swagger' factor involved which cannot be measured, the best players for each of these positions are instinctive and skilled, i think we all know that the Patriots are much better are judging talent based on how much beef it has, Bill understands leverage, technique and measurables.
In signing Emmanual Sanders to an offer sheet, the Patriots are admitting their weakness in identifying WR talent in the draft, particularly in the 3rd round.
I think they believe Sanders has great potential in their system, at least for the role they need them in which is the quick and short pass game, the most important features of any receiver the Patriots will be looking at with be the ability to get open and the ability to produce YAC, As we all know, Brandon Lloyd was terrible at producing YAC because of his propensity to fall down immediately after catching the ball for fear of being hurt otherwise.
I've said for years that Tom Brady's ability to deliver the deep ball has deteriorated for years now and that even if the Patriots had a 'burner' on the outside, he wouldn't be able to reliably complete a pass to them often enough to justify bringing in a big time big money WR, this isn't to say that Brady is terrible, only that he is much better at making decisions and reading defenses than anything else now and having big receivers with good hands and the ability to get open very quickly is a better asset for the Patriots than anything else, because if you get open, Brady can find you, but if you are open deep, he might not be able to reach you.
Sanders has been in the league for years now, he knows what the pace of the game is already so that won't be a factor like it would if you brought in a WR from the draft.
If the Patriots fail to acquire Sanders we'll probably be looking at bringing Lloyd back and hoping he doesn't blow up the locker room.
