JohnnyDoeBoiler is dead on correct. I agree with him in total minutes part and I agree with his starting five. Davis is not ideal at 2-guard, but he has to start: he's team leader and Big Ten Defensive Player of the Year. Now I could see maybe Painter convincing Davis to put the team first and have him fill in as the main back up at both 2 and 3 and Davis would still get tons of minutes and that way Mathias or Stephens could then start at 2-man. But some people are not going to happy with their playing time next year. And I hope, I really hope Painter doesn't try to play too many guys trying to keep everyone happy next year. Playing too many guys cost us, at least, a couple games during the pre-Big Ten season.
The starting (and main lineup -- the same guys who will be playing the last five minutes unless fouls or injury) will be, I predict...
Hill is gonna start at 1-man. He was brought in to be the point and he's gonna be the point with a very capable Thompson backing him up.
2-man -- this is a the difficult position. Davis is not ideal, but he has to play, unless what I stated about him subbing a ton at 2 & 3. But for now , I predict that Davis starts and either Mathias or Stephens backs Davis up, but only one of them is gonna get major minutes. Either Stephen or Mathias is going to be a 3rd-stringer next year and that is not going to be many minutes. Both of them are basically only shooting guards and won't find any quality minutes at the point or at 3-man because there are better options as backups at 1 and 3. Either Mathias or Stephens (or maybe both) are not going to be happy with their minutes next year.
Edwards starts at 3-man. An outstanding prospect, and even more than Davis, our best all-around talented and skilled player. Davis is the back up 3 (probably Davis's most natural position) and that allows minutes for Mathias or Stephens at 2-man. Smotherman is not a good enough shooter to play here, and if we need a 3rd backup at 3-man, it would be Stephens. We can get him some minutes that way.
Swanigan is the 4-man and he plays a lot, 30 minutes a game. Forget all that stuff about him earning the minutes .He will earn them and he will start. When you get a five-star player, you start and play him, or you don't get any more five-stars for a while. Edwards is the backup 4-man, with Davis now playing 3-man, and freeing up more minutes for Mathias and Stephens at 2-man and some 3-man when Davis is out.
5-man is easy. Hammons starts and Haas as backup, and if needed Taylor is the 3rd stringer, but not many minutes there.
Not a lot of minutes for Taylor, Smotherman, and either Stephens or Mathias. Taylor will have to wait a couple years. Smotherman will have wait and accept that, for now at least, Painter has recruited over him and there's few minutes available, and either Stephens and/ or Mathias are going to have to accept the lack of playing time to some degree also. Cline has zero minutes available at 2-man; he will have to redshirt and Weatherford probably also.
I think Purdue is a top-15 team next year. Certain players, who had plenty of minutes, when Purdue was an average or below-average Big Ten team are going to have accept, that for now at least, Painter has recruited over them, other players will have to develop and get playing time later.
