The player that Keegan Murray reminds me of is a bigger Paul Pierce. Both were not elite athletes, but smart, heady player who can score the ball in bunches. I think Murray can be an alpha 20+ pts per game scorer in time. He's not flashy, but he's very active and smart player that will get you 20+pts and 7+ reb a game once he hits his stride.
I was thinking along similar lines as a comparison. And I also think the added defensive value of a combo 3/4 capable of defending three positions is what pushes him to the top tier of this draft for me. Nobody else in this draft has both the all-around scoring aptitude and the defensive versatility that Murray does. I can see why people are comparing him to Harrison Barnes but it's also worth noting that Barnes never had the scoring output in his two years at North Carolina that Murray did this season.
