The reality is, the NYG were never that great. They were a hot team for a 4 game stretch in two different post-seasons and people think they are better than they really are. They were 10-6 the first time and were fortunate that David Tyree made arguably one the craziest catches of all time. The second time they were 9-7 and Wes Welker dropped a catch that would have helped crown the Pats champs.
The reality is New York has never been better than 12-4 under Coughlin. This isn't like this team went 15-1, 14-2, 13-3. They were never truly great.
