Missouri v Ole Miss T question

[ballgame99]

Early in the game Bowers got a T for hanging on the rim on a dunk, then in the second half he got a T for pushing a dude in a scrum that resulted in an Ole Miss ejection. But he didn't get ejected. I don't think they counted the rim-hang T against his personal fouls either. Is this an NCAA thing?

There was also a play where he grabbed the rim after an attempt, they called BI and counted the bucket even though the ball had already bounced off the backboard and was no where near the cylinder. Shouldn't that be a T?
