I'd argue that a team would be less likely to foul without a timeout. Obviously it happened both times regardless, but in the 10 seconds that go by, it's probably more likely that none of the players would realize to foul than a coach calling a timeout and telling his players to foul. Water under the bridge now, we blew it both times.
Side note, I feel for Brian Walsh. #1 shooter in the MAC and missed the game winning shot in each of these games. That's gotta be rough.
