Bona will be fine even after the loss. They're an elite defensive team who had an off-night against a team (namely one player) that was absolutely unconscious from 3. They won't run into another team again this year who will shoot 50% from 3 against them. UNI was well-coached - moved the ball well, had a big who can shoot 3s to stretch the floor, didn't turn the ball over, always made the extra pass. The thin bench is a concern, but as we see with teams like UB, Ohio, etc., that's not terribly uncommon right now.
The A-10 is comparatively weak this year compared to previous seasons, and Bona should lose no more than like 4 games in conference. You never know, but I'd be surprised if they didn't somewhat roll through the conference this season. Say what you will about early Kenpom rankings, but the 2nd-ranked team in the A-10 is only #73 (Richmond). Bonnies are likely far and away the best team in the A-10 this year.
