Player of the year vs MVP is important to consider here. If PoY I would want to see stat lines alone and I think that's an easier answer - Lipscomb and Dollander probably? MVP is a more thorough consideration taking into account the impact the player had on the team. For which I wouldn't rule out the two above, but would include Gilbert, Beam, Walsh, Russell, Beck...Honestly not sure if that captures all in consideration, but would be very hard. Let me try...
co-PoY: Lipscomb & Dollander (seriously both guys stats are/were incredible)
MVP: Gilbert
Freshman of the year: Drew Beam
