Just the opposite. I've been going to the tournament for 30+ consecutive years. What happens is when the underdog starts winning, instead of 2,500 fans behind them, it turns into 20,000 fans behind them. The underdog gets a huge jolt and the favorite panics.I would think this could lead to more upsets, no? Kansas in Omaha, Gonzaga in Spokane, Duke in Greensboro lose a lot of crowd support in their early games.
