WATCH: Xavier Tillman throws down one-handed dunk over Rondae Hollis-Jefferson

Xavier Tillman had his first big NBA poster dunk for the Memphis Grizzlies with a big slam over Rondae Hollis-Jefferson.

Xavier Tillman has been one of the most surprising rookies in the NBA this year, at least for people who didn’t watch him play for Michigan State.

Tillman has been the second Spartan to join the Memphis Grizzlies front court, following his old pal Jaren Jackson Jr., and he has been showing out all season. On Sunday, he showed off something he hasn’t done too much of though when he went over the top and dunked on Trail Blazers forward Rondae Hollis-Jefferson.
