USC vs Arizona - Intentional Foul

[Berkut]

I was rather amazed at this after seeing the replay. I assumed while watching that Wise punched him or did something extreme - I cannot understand how they could mess this up so badly. I am still hoping there was something that wasn't apparent on the TV.

The thing is, it isn't like the straddling hium was an accident or something - he clearly stepped forward and stood over him to keep him from getting up. How can you let that go?

Even if it isn't a T, why isn't it an immediate blocking foul on the USC player? He certainly does not have a legal guarding position.
