I haven't watched the entire game (busy with other stuff) but I watched the basket interference play, Geo's shot with 3 seconds left and the shot from the corner that Iowa hit.
When I saw it in real time, from the BTN broadcast angle, it looked like basket interference. When I saw it in super slow motion from the camera mounted on the basket, the ball appeared to be off the rim. A small portion of the ball may have still been in the cylinder though.
Per the rules, unfortunately, the officials can't review this type of play.
On the last play of the game I was surprised that Rutgers didn't guard the Iowa player throwing the ball in, but the thing that really had me scratching my head was Doorson defending Wieskamp.
