The first hack a dok occurred when he took his normal position in the lane, and got pushed in the back. The foul was clearly intentional, but there's no way an intentional foul gets called there. Luckily, he made both free throws.
After that, he went wide of the lane on the baseline, and actually stepped out of bounds when his defender came near him. Perfect. Any foul there has to be intentional, and thus TCU didn't commit the foul.
He can stay in the game for defense and rebounding by removing himself from the offense. Not a great solution, but better than having him on the bench.
