Baseball, as we know, is the sport of heaven. Other sports are not as good, and here is how I would change them.
Basketball: The interminable series of fouls and free throws makes the end of basketball games ugly and boring. I was trying to watch the end of the NC State vs. Marquette game and almost died of boredom. It must have taken half an hour to play the last three minutes of the game. Fouls in the last minute or two of the game should result in free throws plus possession of the ball for the team that gets fouled.
Soccer: I normally work in a country where soccer is king, so I have to at least pretend to like it. But flopping is awful and really detracts from any enjoyment one might otherwise draw from the game. Every match should be automatically reviewed by a video ref after the match is over, with sanctions imposed for flops. Bad flops earn a yellow card, meaning that the flopper starts the next game sitting on yellow. Really bad flops get a red card, meaning the flopper is suspended from the next game. That would end flopping in a heartbeat.
Any other ideas?
EDIT: What I would also change is not having a typo in the thread title.
