The non-connecting thrown elbow is, in my book, usually quite different than a punch or other types of obvious fighting. It's normally a "get off me" elbow, it shouldn't happen, but I don't see this usually requiring an ejection.
As for the OOB run, it is the correct call, and in NCAA, going to POI, it seems that it is not nearly as severe a penalty as in NF. In NF you give 2 FTs and ball. In NCAA, I guess this would result in eam A getting the ball back at POI with whatever time remained on the shot clock. That makes it a slightly easier call. Although, since this is not a well-known rule (among refs, players, or coaches), I don't think it is fair to characterize it as easy, Mark
