Depends on their depth. A team going 9-11 deep with some quality can keep up a fast paced style the entire tourney. A 6-8 deep team would struggle. Also can depend on whether they get a blowout game or two before the final. The opponent in the final will have their depth and conditioning tested in the earlier rounds too. Superior depth can be the difference in the tournament. When we lost to Davidson in the 2002 finals we had guys cramping from fatigue in the second half. They had a sub come in and score 22 for the difference in the game.
