Bad throw, questionable call to throw the fade to the far corner after just throwing a fade the other way, but either way it was well underthrown. Tough to put that all on Zeb's shoulders as that's not an easy throw, maybe a back shoulder thing or attack the middle with the slot receiver? Not an OC but I think it's asking quite a bit of a young QB in a high pressure situation.
The INT call was probably correct, I think Murdock had a hand on it but no shared possession until he took it away when they were on the ground.
The real travesty of that drive was the lack of calls on OSU's secondary that looked veeeeery similar to what we were called for twice on the 2 point conversion.
