This is not fair to Jamal as he has yet to play a game for Kentucky.
Wiggins was the #1 pick in the draft because of his freak athleticism. Murray does not have that, however Jamal may have a bigger impact on the college level and end up being the better college player. Wiggins will be the better NBA player.
If we are comparing the 2 at the college level then Murray could realistically be better, only time will tell. It's great to have these athletic guys but it's also nice to have guys that know how to shoot the basketball.
My pick for college? Give me Murray, he chose to be here.
