The Cleveland Cavaliers are unlikely to commit to any single player with the first overall pick before the draft.

Joel Embiid will be the first player to workout for the Cavaliers, but they'll also look at Andrew Wiggins and Jabari Parker.

"We have to keep our options open," the source said. "Once you commit, your hands are tied. The good thing about the No. 1 pick is that you have lots of options. Embiid is a great prospect and he might very well be the choice at No. 1. But until you see all three and, more importantly, until we understand the trade market, it just makes no sense to make any promises."
