Strengths
Right-handed… Mack suffered through a mid-season slump before finally hitting his stride on the big-stage of the Horizon League Tournament and NCAA Tournament… He has decent size and a filled-out frame, and is capable of playing either backcourt position. His numbers have taken a bit of a dip as the go-to guy for Butler this season, taking over the role left behind by Gordon Hayward. While his efficiency percentages are down, Mack is becoming a more developed offensive player. Instead of relying for his opportunities in transition or in spot-up situations, Mack is a more aggressive scorer off the dribble in pick-and-roll and isolation situations. Especially in pick-and-roll situations with the offensively-developing Matt Howard, Mack looks very comfortable running the offense, capable of hitting Howard en route to the rim or reading the defense and kicking it out to him for a perimeter jumper. He shows good patience taking what the defense will give him and waiting for the play to develop… He has 3-point range and the ability to put the ball on the floor and take it all the way to the rim. When he drives the lane, he has good overall body control and can finish with either hand, although, he almost always prefers to go right and finish with the right hand. When the defense cuts off his penetration, he does a very acceptable job coming to a quick stop and pulling-up off the dribble.
Weaknesses
Mack is about an inch or two undersized for the ideal 2-guard size, with just average quickness and explosiveness, which is why he projects to be more of a combo guard than strictly a shooting guard at the next level. He has great size and strength for the point guard position, but spends a majority of his minutes as a shooting guard in Butler's offense… Another question related to Mack's position at the next level is who he will be able to defend. He most commonly matches up with opposing shooting guards and small forwards, using his strength to body them up, but will he be able to do the same to quicker point guards? He doesn't have great lateral quickness, which leads us to the belief that he'll be just an average defender at the next level.
