The rule sucks, but that's not the point. Even with the general suck of the rule, what happened on that play is not DPI.
The poorest part of the play was that he misjudged where he should originally turn his head. He did it to the right instead of the left initially, realized he had to turn to the left, did so, Edelman altered his route to get under the ball which drew the contact (again, incidental), and sent him to the ground. It would have been unfortunate for us had the refs not messed up and just waved incomplete, but it wasn't. I'll take it as it put the team in striking distance while the game was still close, but it was still a piss poor call.
No, they don't unless you really want to try everything in your power to make a case in spite of overwhelming evidence that it was a bad call. Like I said, you're smarter than this. I'm really not sure why you're digging your heels in on this one.
