The Bucks have the worst record in basketball, which doesn't guarantee the top pick. But if the ping pong balls dropped in place, they'd lean towards Kansas center Joel Embiid, according to ESPN.com:

Bucks GM John Hammond will choose the player he thinks has the best chance of being a star. Right now it's a three-man race, but sources indicate Hammond loves the skill, size and rapid progression of Joel Embiid. The Cameroon native is new to the game and has tremendous upside. Embiid can help the Bucks on both ends of the court, and while he recently told ESPN.com he might return to school, most feel that he'll be in June's draft.

Unknow who the parties are involved in the "three-man race," but one would assume it's Embiid, Andrew Wiggins and Jabari Parker.
