I used that theoretically. The shot after the tip out could have been a 3 pointer for the win. Also, someone could try to foul and have someone jack up a prayer to get a 4pt play out of it. So there are 2 rare scenarios where you could lose by fouling instead of simply guarding the 3pt distance without fouling anyone. I suppose there's also the risk of giving up free throws and then having your inbounds stolen with a quick shot for a loss. That's the stuff that scares coaches off. They're risk averse. Same mentality we see in football with punting on 4th down from the other team's side of the field.
I think with Tad it's more of a matter that it's another scenario he'd have to spend practice time on when he doesn't need to. The numbers are close enough either way so that he'd rather just play it straight while re-enforcing the mindset that CU stops people without fouling.
Ken Pomeroy looked into this and it seems he'd rather play defense based on what the numbers say. When you have to shoot a 3 and the defense knows it, you only make about 16% of them. And offensive rebounds off free throws occur at about a 40% rate when the offense is in desperation mode to get that board. But all the numbers shake out very close either way.
