Well, that didn't take long.
McCallum played in three games for the Bighorns, averaging 22.0 points (.455 FG%, .308 3pt%, .667 FT%), 5.0 rebounds, 3.7 assists, and 1.3 steals in 38 minutes per game. While the Bighorns lost all three games, McCallum was the team's leader in scoring in each game.
I wouldn't be surprised if this was the first of many such stints in the D-League for McCallum. The team is on a long break right now with a couple more home games immediately after, so it's a good opportunity for McCallum to be in Sacramento practicing with the team.
From what I've watched of his short stint in the D-League, McCallum shows promise as a scorer, although he's a rather streaky shooter. He excels in pushing the fast break, but could do a better job of setting up others. He's extremely athletic and has a lot of potential on the defensive side of the ball when you combine that athleticism with his excellent size and length.
