I think MAAR is 100% locked in as a starter. I don't see JB bringing in a grad transfer to overtake a Senior two-year starter. That person may eat his minutes but not start over him.
I also think we can pencil in Matthews as a starter. If a grad transfer has to come in and starts over him, then we're probably in trouble.
At PG, yeah I can definitely see that being open. I think if it was a grad PG, they'd have the opportunity but in my opinion they wouldn't bring in a starting type PG transfer.
