Watching Justin Anderson tear it up will always be bittersweet for me. As a Toronto Raptors fan, I was super excited to see him available when the team’s pick came up at No. 20. However, my vigorous campaigning and hyping up of the Virginia standout appears to have been futile, as the Raps went with Delon Wright instead. Wright is a fine player, and absolutely worthy of a first-round selection, but there will always be that “what if” with Anderson, who was drafted the pick immediately after by the Dallas Mavericks.

Anderson started slow in Summer League, but as the tournament has progressed he’s shown more and more of what will make him a bonafide steal for Dallas. Anderson straight up dominated in today’s elimination game against the D-League Select team, putting up 23 points on 8-of-15 shooting and 4-of-6 on threes. He’s at just 40 percent from the field through five games, but when you account for how many threes he’s made and his stellar free throw numbers, he’s actually been quite efficient.

Anderson’s numbers are all the more impressive when you consider that Summer League typically favors guys who create their own shots. Most players are out there gunning for an NBA contract, so spot-up shooters often don’t get that many looks. Nevertheless, Anderson has found his groove, and this bodes well for him earning a key role in the NBA.

The best part with Anderson, though, is that his value doesn’t start and stop with scoring. He’s a very promising defender, and his skills in that department have been on display all Summer League. He had an absolutely nasty block on an attempted Tariq Black dunk against the Los Angeles Lakers, and has flashed great mobility for his size on the perimeter. His size and skill set are basically unmatched in this year’s rookie class.

Look for Anderson to get some serious burn in 2015/16. The Mavericks are not deep as it is, and Wesley Matthews, Chandler Parsons and Deron Williams are all injury risks. I think he’s a dark horse candidate to make the All-Rookie First Team, and as close to a can’t-miss prospect as you can get for a No. 21 pick.
