Yeah, I would just like to know the reasoning for it not being overturned:
Was it because they didn't feel there was clear evidence that he was out of bounds? I have a hard time with that one, given it was pretty obvious in real life, let alone the one replay they showed. Also, the TV guys didn't seem to have a doubt that he was out of bounds before catching the ball (though they didn't seem to connect the dots to that being illegal and a non-catch).
Did they not review that part of the catch; just look to see if he got his feet in bounds after catching it? If so, wouldn't starting out of bounds as part of the catching action be part of that decision?
Did they think that the "illegal touching" part was not reviewable? If so, it appears they would be clearly wrong in that situation.
Did they not know the rule? Sadly, I wouldn't put it past ACC refs.
Did they realize that it wasn't a TD and just say "screw it, we aren't going to change it"? Maybe because of the crowd?
