I would also prefer a consistently rounded 3 point line and not just for aesthetic reasons. It seemed like every game there would be at least one turnover for Michigan because someone accidentally stepped out of bounds before shooting a 3pt shot from the side, and I saw that happen fairly often with other teams, too (maybe it will be reduced in the future, but I'm not sure). Making that change would make it more difficult for teams to get open 3 pt shots, but I'm fine with that.
I'm not sure what the solution is, but something should change with the bonus system. That said, the women's basketball rule with their quarters is even worse, and thankfully the men's game didn't adopt that proposed rule.
One idea that comes to mind is that for non-shooting bonus fouls, players get to attempt 3 FTs if they're fouled outside the 3pt line. This would disincentivize excessive fouling until the last minute to 30 seconds of the game.
