I don't know that Samuels stays out of foul trouble enough to average 25+. Seems we'll need him in the post more often now and that will lead to potentially worse foul trouble than last year.
I like 95 to play between 10-15 min a game. I think the lack of anyone who can create or even drive on offense will necessitate that. I would expect at least a full 40 to be split between him, Rodriguez, and Irving based on this. Not saying that Irving is great offensively, but he'll play offense with confidence, attack, and hopefully draw a couple fouls.
