Dan, great post, as always. The rule appears to benefit Iowa on their face because Iowa is a team that likes to press and tends to shoot fairly early in the shot clock. However, I always worry about unintended consequences. In this case, you could see more teams ultimately adopt an Iowa approach to the game. For example, more teams might decide to press, like Iowa, simply because it takes several seconds off the shot clock. Conversely, more teams might decide to push the ball up the floor faster because there is less time on the shot clock. In total, I can't see these rules hurting Iowa by any means, but will be curious to see if it causes more teams to play like Iowa, which would neutralize any possible advantage.
Along a similar vein, my other thought is that to the extent the new restricted-arc rule favors more athletic teams, I'm not sure if this will help or hurt Iowa. Certainly Fran McCaffrey wants to play an up-tempo game with athletic players. However, this is Iowa and it is not easy to recruit those players here. With the exception of Marble, we haven't had many during the Fran years though I recognize the incoming Freshman seem to be headed in that direction. Still, hard to see Iowa consistently out recruiting Iowa, Michigan, MSU, and Indiana (or even Illinois) for these type players. So to the extent we get a more NBA style game not sure that helps Iowa all that much.
Overall, I think Iowa will do just fine with the new rules. And I think they may slightly improve the college game. The limited timeouts should help. But I really don't want to see college become the NBA. If I wanted to watch the NBA, I'd watch it. A 24 second shot clock sounds horrible. Teams wouldn't have any time to run an offense to get an open shot. Instead, they probably just jack up contested jumpers like in the NBA. And 6 fouls also makes no sense unless the College game goes to 48 mins, which I don't see happening.
