Would you accept this trade?

YES. Big Ben is not far behind Brees. I had him last year and he gave me 20 points pretty regularly. With the uncertainty in the Green Bay backfield Mendenhall has more value than Grant. And Antonio Gates is the best TE in the league, anytime you start the #1 player at a position you're at an advantage. WR are easy to replace, and Welker isn't the same.
