Personally like halves format, although I am fairly ambivalent. More than anything, I would prefer a mechanism to discourage end of game fouling.
Agree about discouraging reviews. Not sure how to improve clock operators/officiating in general though; basketball has to be toughest of the big 4 to officiate and there are so many games, CBB is going to end up with shitty officials. Try to minimize how much they can interject themselves.
