Everyone wants to propose changes to "fix" the game of college basketball. However, the sport doesn't need widespread changes. Just band-aids. Here is my personal modest proposal to fix the issue of low scoring and too many breaks.
1) Shot clock to 30 seconds, from 35 seconds - no brainer.
2) Media timeouts every 5 minutes instead of 4 minutes - instead of 4 media timeouts per half, you get 3. To compensate for the lost commercials in the 4th media timeout, extend each of the 3 media timeouts by 30 seconds. This has the added side-benefit of baiting coaches to more often call timeout during a game instead of hoarding them all for the final 2 minutes.
3) Ban calling timeouts after a made basket - the vast majority of late-game timeouts happen once a team makes a basket and then calls timeout, in order to set their press defense. Just simply ban it. Once the ball is in the hoop, it isn't yours, and you shouldn't be able to call timeout.
There you go. 3 simple fixes to help speed up the game. It's not hard, NCAA.
