A shorter shot clock would just mean every team would recruit and try to play faster. I prefer the current clock wher you can't sit on a 4 point lead like Indiana used to do in the 80's but you can also choose to run an offense. It's to our advantage to bring a fast pace game to teams like the big 10 teams that are't used to it.
A shorter shot clock would also widen the gap between the haves and have nots. In order to win games an overmatched team can slow down, limit possessions, and possibly be close near the end. Force those teams into more possessions per game by both teams and it drastically reduces the chances of a very big underdog to pull the upset.
Take Butler for example... lost in the finals to Duke 61-59 and to UConn 53-41. Ugly basketball to be sure... but the only way they even had a chance to GET to the finals was winning games by scoring 54, 63, 63, 52, etc.
I think a shorter shot clock HELPS us. But I don't necessarily think it would be good for the game. I like parity more than I like seeing Duke score 100 points on some hapless foe.
