For you to say that you could WITHOUT A DOUBT see that ball was not in is showing a bias.
As a Cowboys fan, I can understand it when it comes to the Steelers. But as a football fan, for anyone to pass that off as a fact is reaching at best.
That ball was a matter of inches from being either over or not, it could've gone either way. But no one can conclusively say it either way. If the original spot had been just outside the goal line, the call would've stood there as well. Why? Because their was no conclusive evidence to overturn the call.
Besides, the angle that showed the play the best wasn't exactly at the best angle which would've been directly down the line.
