If you look at Geno's time as NT coach, the minutes on the team were quite well distributed between the top ten players in each competition. It was pretty clear who the starters were, but the substitutions were frequent and many - he tended to substitute a few players at a time so chemistry was maintained within the substitute pool as well as within the starters - that is always an issue, the more time spent with specific players in games the better chemistry is developed. The last two on the bench were often more 'emergency' players based on a specific game situation, and injury, foul trouble, or simply trying to 'blood' a younger player.
I think if you look back at the 1999-2002 period at Uconn you also see how Geno handles a loaded roster - no one was getting 30 minutes a game, but a lot of players were in the 15-22 minutes per game range. Jessica Moore in 2001-2 was getting 18 minutes a game playing behind Williams, Jones, and Cash, so she was ready for 2002-3 when they all graduated. Williams, and Jones had played significant minutes behind Shumacher in 2000 and 2001.
