There is no debate here - you foul. Every. Single. Time.
Marquette being 0 of 14 from three literally has nothing to do with anything. The fourteen misses prior has no baring on the fifteenth. Don't point to a lone example of a coach fouling and it not working out - that's terrible logic. I can do it too - ask John Calipari how not fouling in that situation worked out for him.
I was screaming at the TV for UConn to foul as soon as Boatright's jumper went through the basket. If UConn fouls with three seconds left, the chances of Marquette hitting the first free throw, missing the second on purpose (without a lane violation), grabbing the rebound, and then getting up a shot that is probably off-balance (UConn would have at least four guys in the paint) are slim at best. Yeah, the chances of Cadougan tossing up a shot from three feet behind the three point line that goes in are slim too, but the bottom line is UConn wins that game if they simply foul.
