Here's why I think Luuked is right in his analysis that it was a bad decision by Brady (though I think he's wrong in slamming Kontra for his view.)
1. Brady was under severe pressure, and had to throw the ball off his back foot which vastly reduced the velocity of the throw
2. Devlin wasn't wide open. In fact he was barely open at all. I think if the defender had made a better play on the ball it would have been picked cleanly and likely have been a TD.
3. But mostly it was a bad decision because of it wasn't a good situational throw. The Pats were ahead by 2 scores at that time IIRC, and were well within FG territory. Why take the risk that he did? If he simply eats the ball or throws it over Devlin's head. Gotkowski kicks the FG, the Pats are up by 3 scores and the game is over.
There might be situations where that throw is justifiable, THIS was not one of them.
Now that being said, the ball DID get to Devlin, (though I don't know how) and it was very unlucky that it deflected right into the hands of a defender. Brady has had at least 3 deflected picks this season, maybe more. The other 2 were ALL the receivers fault. This one wasn't. JMHO
BTW- I'd be willing to bet that if you asked Brady about the play, he'd say that he shouldn't have thrown the ball, or at least say he should have thrown it better.
