I think it will be Winston or possibly, if PSU somehow wins the league over MSU, Stevens. Smith doesn’t have any gaudy stats, so if MD wins it, I would guess they’ll give it to Winston (or possibly even Cowan, deserved or no).
No one’s really talking about Oturu (probably because MN isn’t getting anywhere near a conference title and may miss the tourney), but he’s leading the league in rebounding and blocked shots and second in scoring.
