It seems that those concerned with out lack of depth (including yours truly) point to Nash and Scott as the answers. Neither of those two can really play in the backcourt to give Jackson or McAlarney a breather. While Nash is a good rebounder, you definitely do not want him taking the place of Harangody on the offensive end.
The result is that we have three guys playing the whole game (Jackson, McAlarney, and Harangody) and three more experienced players (Ayers, Hillesland, and Zeller) splitting 80 minutes of game time.
The players who seemed to be tired yesterday (Jackson with his turnovers, McAlarney and Harangody with cheap fouls) don't play Scott and Nash's positions.
