You're right. That's the reason y'all lost the game. Better call Goodell.
Final Score: 34-31
That play resulted in 7 points for Dallas.
So yes, that play literally is the difference between winning and losing the game. Is it the SOLE reason the Rams lost? No. But lets not act like that wasn't a clear hold on a TD in a game Dallas barely won.
There were other reasons we lost that game...such as Jared Cook dropping a walk in TD and Austin Davis falling apart (as he did all year) in the 4th quarter in crunch time.
That all said, it's going to be hard for a Cowboy fan to deny that your team didn't get away with a lot of holding last year. Like Seattle does with their DBs, Bill Callahan is quite good at instructing his OLs how to hold and get away with it. And they do it incredibly often. They basically dare the refs to make the call. And the refs don't. It's the same philosophy that Seattle has with their DBs (as I said earlier).
And why would I call Goodell? He's probably on the Cowboys' party bus with Dean Blandino.
