The smallest of the three participants, Portland's Anfernee Simons can get up with the best of them despite standing just 6-foot-3. Though Simons has been unable to string together consistency during his short NBA career, he has flashed elite athleticism. We're always going to see some creativity, and maybe even props, during the Dunk Contest. Simons could be the one to come up with the most original dunk on Sunday and should provide some great entertainment. Knicks rookie Obi Toppin entered the league with a reputation for monster dunks from his time at Dayton, and now that will be put to the test on All-Star Sunday. The Naismith Award winner a year ago as the top college player, he has long been expected to participate in the Dunk Contest. A 6-foot-9 forward, Toppin is likely to be the only participant throwing down power dunks against two smaller, freaky-explosive athletes. Toppin is no slouch himself, however, and should wow viewers with his reputation preceding him.
