I think the only way you would play Moe at the 4 next year is if Livers isn't ready to contribute. If he is, I would rather see him get the backup 4 mins and Teske/Davis backing up at the 5.
Last year, Moe avg. 24 mins per game overall and 28 mins in conference games. If he can limit his fouls issues, he could probably play 30 mins a game but I don't see him avg. more than that. I think asking Davis and/or Teske to play more than 10 mins combined might be expecting too much.
I guess the question is how many mins. can Livers handle next year. You have 80 combined mins at the 3/4 available. Can you have a 3 man rotation at those spots between Matthews, Duncan and Livers? The other option is Watson but obviously he's an unknown as well.
