More of a scoring point guard than true distributor
Will likely struggle guarding quick point guards
Summary: Shelvin Mack has received a ton of national expsoure the past two seasons due to Butler's runs to the Final Four which should give NBA scouts a good feel for his potential at the next level. He is the definition of a combo guard who will need to learn how to be more of a true point guard if he wants to maximize his opportunity in the NBA. He should get late first-round looks but could fall into the early second.
Player Comparison: Willie Green. Green is an undersized off guard in the NBA who has never been able to grasp his opportunities as a point guard. He and Mack both rely on their strength to help them on both ends of the floor. If Mack can work on his pure point guard skills, he should be able to run an offense in the NBA rather just be an undersized two.
I don't get the Garrett Sickels pick in the 3rd when your own evaluation of him clearly states that you believe he his a 3-4 OLB in the NFL and a day 3 pick at best. I think Dallas would rather take the risk with Carl Lawson in that spot than give it to a career rotational player at best.
