"The Giants were lucky that Gronkowski had a bum ankle." Response: our best TE played throughout the playoffs on a bum knee...without a bye week. Then we see your bum TE ankle in the SuperBowl and raise you two ACLs.
"The Giants were lucky that Welker dropped the pass." Was Brady a bit nervous throwing that ball? Was it our pass rush that made him nervous? Or, our safety moving in the right direction? Luck indeed. I'll see your lucky dropped pass and raise you a pass interference penalty not called.
"The Giants were lucky to recover two lost fumbles." I'll see your lucky fumbles and raise you with teammates who hustle all over the field until the whistle blows.
"The Giants were lucky the Pats had 12 men on the field." Well, if they had 11 men on the field, it's possible Cruz scores a TD on that same play and there is no fumble!
"Luck." It's the easy refuge for losers.
As a Giants fan in the 1960s and 70s, I always thought that the Giants had bad luck and the Cowboys had good luck. They always seemed to have the ball bounce their way. The truth is that they had better teams. Same goes for the Giants now. Miles Austin overthrown. Luck? No. Don't overthrow a guy who's wide open on 3rd down when a 1st down wins the game. Winners make their own luck and losers shake their fists at their unlucky stars.
