There's a reason the president of basketball operations Neil Olshey traded the Trail Blazers' No. 15 and No. 20 picks up to select Zach Collins out of Gonzaga in last week's 2017 NBA Draft.

Add to that a 47.6% clip from three-point range during his freshman season and it's easy to see why Olshey coveted the Las Vegas native.
