Absolutely NOT.
I've said this several times and I'll say it again:
This is the farthest thing from an excuse, but the Patriots have been purely UNLUCKY.
From the Tyree catch in 07/08, to a Welker drop in the SuperBowl last year. Had those 2 PLAYS gone the other way, you could EASILY argue the Patriots would have won the game, and Tom Brady would have 5 SuperBowls.
The injuries have also been unbelievably bad. Gronk last year of course (IMO we'd won the SuperBowl with him healthy. That INT definitely wouldn't happen) And then Gronk & Talib this year once again when it matters most (they are top 3 guys on their respective sides of the ball) We can only go so far with our top guys out of the game, and constantly having to adjust.
EDIT: And did you NOT watch the SuperBowl last year? He set a record for 16 straight completions, and was within 1 play of winning after taking the worst defense to ever make it to the SuperBowl. WRs and no-name guys playing on our D last year! He also has the most yards in playoff history and most wins in playoff history. He's simply lacked help. Montana had how many hall of famers alongside him? 5-7? How many do you think Brady will have had after his career is done? Maybe 3 including Moss and his own coach?!
You want to talk about having bad luck after the tuck rule, and the Panthers kicking the ball out of bounds on a kickoff in a Super Bowl that probably would have went into overtime. Now, THAT'S luck on your part, especially the tuck rule, which they didn't give to Manning in the playoffs this year, BTW
Another way to look at it is that the other teams made plays. For example, the Ravens tipping Brady's pass at the line was not "bad luck." That was the Ravens making a play...same goes for the Tyree catch. The other team made a play.
What you described is the essence of making an excuse...not the "farthest thing from an excuse." How do you think the Ravens felt after losing to the Patriots in last year's Championship game? They had the winning touchdown DROPPED at the end...Lee Evans did not hold onto the ball like he should have...if he'd brought that ball in and held onto it for dear life, no way it gets swatted out of his hands IMO. Then the Ravens miss a 32-yard fieldgoal to tie it up and sent it into over time. Was that good luck the Pats were able to make it to the Super Bowl LAST YEAR?
And EVERY team has injuries every single year to some key guys...everyone. The Giants lost ALL of their starting CBs pretty much before the year started last year, for example.
Lastly, Brady has won Super Bowls with no-name receivers. In this game, Brady had more weapons at his disposal than most teams. This year, the Patriots finally had a running game. Brady gets more protection than most QBs too...it's ridiculous how much time he has sometimes. The Patriots had the #1 offense in the league this year, and you still want to complain? The Patriots scored a ridiculous 557 points in the regular season this year. One guy did not do that, even though Brady was the catalyst.
Face it, the Patriots were just outplayed in this game. That's all there is to say about it.
