When it was first announced that the NBA was partnering with ESPN for a nationally televised game of H-O-R-S-E, Andrew Marchand of the New York Post reported the unofficial list of candidates were Houston Rockets guard Russell Westbrook, Chris Paul, Donovan Mitchell, and Zion Williamson.
Westbrook and Williamson would’ve made for a great Slam Dunk Contest, but seemed rather odd for a game of H-O-R-S-E. For this reason it seemed almost certain that the list would get revised a bit, which is what appears to be taking shape.
