A couple of the hold calls were questionable, but I could see them going either way.
However, one of the called holds did not seem like a hold. It was a block and the rusher seemed to trip over another lineman's feet and Guyton landed on top of him.
That facemask penalty on the Giants (unless I missed something) should have been on the Cowboys.
There was pass interference on both teams that were not called.
I think the referees were really bad tonight, but I don't think it was completely one-sided .. just tilted in the Giants favor.
