James averaged 20-40 yards less per game in AZ.
Wayne was 3rd/4th option, at best, under Manning(James, Harrision, Stokely, Clark, Pollard). And he still had his best seasons with Manning.
Garcon, same as Wayne, was 3rd/4h option under Manning. Targeted 11+ times per game in 2013. Other than that, same guy every year. Already said this.
Decker, uh, what? Only good season was with Manning.
Please, nomay, your argument is stupid. Manning makes them better. Just like Belicheck makes Brady better. I'll add that Manning has NEVER has a mismatch like Gronk or Moss. Those two can't be covered.
