I'm not sure they do, considering that most everyone here has always referred to Lipsey as the team's primary PG, even though Gilbert was handling the ball (both bringing it up the court, and in the half court) quite a bit more this season than Lipsey was, perhaps until Gilbert's struggles in conference play.People know the differences between PG and 2-guard or wing. You are overrating how important playing a tried and true PG is, to literally spell our guards for 4-5 minutes a game, due to it being an emergency situation as a result of injuries.
But, I generally agree with your point here. Kelderman was not doing things that someone like Heise or Nojus wouldn't have been capable of doing in terms of handling the ball. I think Kelderman got the call because Otz trusted him more defensively. And to Kelderman's credit, he was super active defensively in his minutes on Saturday.Kelderman wasn’t facilitating the offense against KSU. He was bringing the ball up across half court (unpressured fyi), passing it off, and then getting the heck out of the way to create space.
I get the defensive component, but if Nojus isn’t capable of being able to do what Kelderman did, that’s a red flag.
I'm not sure I'd call it a red flag for Nojus, but it's at least a yellow one.
