I don't think that type of a lineup is on the Staff's radar. MAAR is not a PowerConference level PG. He "might" be able to steal a 2-3min spurt in a rotation with Poole & Matthews at the 2 & 3 spots (if both Poole & Matthews develop as projected), but only if Poole & Matthews would be able to trigger the offense.
Simpson will open camp as the starting PG --- unless a grad transfer is brought in. Brooks will be given the opportunity to complete for minutes.
Assuming they stay in college, Wagner & Wilson will open the season in the starting lineup. Teske/Davis/Livers will likely compete for reserve minutes among the "bigs."
Matthews likely opens camp as the other starting wing. MAAR likely opens camp as the starting 2-guard. Robinson will have an opportunity to complete for a starting spot --- either bumping Matthews to the bench or bumping Matthews to the 2-guard with MAAR coming off the bench.
Barring a major improvement, there doesn't appear to be a path for Watson to get playing time. He may be a good redshirt candidate with the athleticism to develop into a late-career contributor?
