CAN be. Any foul CAN be ruled an intentional foul. If a player has the ball and you go up and bear hug him, that should probably be an intentional foul.
There are ways to do it. It's why I personally hate the fouling up 3 thing, because those fouls are usually blatantly obviously intentional, and never get called. I think they should call more intentional fouls, but they don't. Grabbing a guys jersey as he dribbles by you, to stop the clock, should be intentional. But you'll never see it called. Ever.
I still stand by my original post. The best thing Santa Clara could have done would have been to foul Garrison immediately after the make. Run into him. Get tangled up. There are a million ways to have done it that wouldn't have drawn an intentional foul call, and Garrison would have been the one shooting FT's, not Oweh.
