If you look at the stats between 2012 and 2011 regular seasons.
Eli threw 1 less intercept, 9 less sacks, and 3 less fumbles lost in 2012 compared to 2011. There were 50 less pass attempts in 2012 but, nevertheles, Eli had fewer "bad plays" per attempt.
The real difference is Eli went from 8.4 yards per attempt to 7.4 this year.
What was gone or the big reduction was in the "big gainers". There is no doubt that it is attributable to loss of Manningham and the injury to Nicks above all else.
I also think defenses took the big gainer away from the Giants this year.
End of the day, the Giants finished 9-7 with a tough schedule and tons of key injuries. I do not think it was as bad as some posters would paint the season. I think people need to be realistic of what we achieved with what we had. I also think throwing people who won 2 Superbowls under a bus (whether it is Eli or TC or whoever) is a little short sighted.
