Well I havent found a ranking of which is best. I did find a list of every school that has the program in the U.S:

Anyways: my reccommedation: go to a school that has a major sports program. Football, Basketball etc.. Also pick schools that send lots of players to professional teams. if u wanna work in the NFL, it wouldnt hurt going to a feeder school for NFL Teams.
imo I wouldnt pick a liberal arts school or small state school that has not really succeeded in any division 1 sports. I might be wrong but If i were majoring in sports management I would def pick the big name schools u see in sports all the time.
Go to a big state school or just one of the big private universities u see a lot on sports games on tv examples: Notre Dame, USC, FLorida, Ohio State, Indiana, Miami, Michigan etc..
