I love McCollum, but he is a bit of a combo guard (like all of the other guards we have). So not sure how great of a fit he would be.
The best fit player for the Hornets and the most underrated player in the draft is Doug McDermott. He is going to be the best, pure SF prospect in the draft. He plays PF for Creighton, but was a 1st team all american and he can shoot the lights out (LINK
). He is exactly what the team needs.
