Westry was a medical redshirt last season. Any reason to not try to have him play circle around the likelihood of a sixth year of eligibility, whether it is likely one would be granted or if he would even want one. If he is healthy enough to play without risk of further injury, he wants to play, and the team circumstances merit it, there is likely no good reason to have him sit.
At the same time, there is almost no reason to have a ten-player rotation. The ninth man right now, Cuffe, is getting minutes beyond providing the smallest amount of rest for Mintz and Starling only if he provides instant impact/a starter has foul trouble/playing a lesser opponent. Cuffe's minutes following the Chaminade game: 3, 6, 15, 3, 15, 18, 5. The double digit minute games in that stretch are Cornell, Oregon, and Niagara. He had an impact early against Oregon and played more against lesser foes, which we will not be seeing the rest of the season. Rotation is essentially already trimmed to eight, especially with the option of playing Copeland at guard.
