Taylor is a shooting guard/SF. I think Bay will see time at both guard spots. I believe the high school player who is being recruited is a PG. So, you could see both Morgan and Bay on the floor at the same time, splitting the PG duties, or the freshman, if he doesn't redshirt, playing the PG role. And then you have to ask about playing time for Carson, Kilpatrick, Tatum, etc. It's a good problem to have.
In figuring out who will start next year, I always give the nod to the kid who's been in the system for a year or two. JC kids just naturally take most of a year to fit into a new system, and to learn how to work hard again on both ends of the floor. I think Busma will be an exception because of his size and physical presence. No matter how you look at it, pending any transfers, grade problems or injuries (and we all remember how excited we were this time last year when Jackson and Maye were supposedly on board), this will be one of the deepest ISU teams in recent years.
(Oh and remember, these kids all bring weaknesses with them, that's why they're at Idaho State. Busma only averaged 9 points a game -- less than Steijn his last year in Juco -- so we can assume he doesn't have much of an offensive game. Bay, as was discussed earlier, has a very low assist to turnover ratio and probably isn't a true PG., etc. But it's nice to be able to mix and match the different strengths of 13 different players who can all contribute.)
