On the bright side, it shows they aren’t horrible and can beat some teams. Although getting waxed by Miami before that doesn’t help that argument as much.
Pretty much yes. You can't foul up three with that much time left. Because you bring what ended up happening into play. They should have been looking to play solid defense and force Clemson to make a tough shot.
Now if the clock had gotten down to three or four seconds and they had a chance to commit a floor foul, then yes, by all means, foul then. But there was too much time left to play that the way that they did.
