That's what doesn't make any sense at all. Wes Johnson is worth a 1st round pick based on potential alone. Even a straight up swap of Johnson for Warrick doesn't make any sense. Toss in a 1st round pick going to Phoenix, and it's just straight robbery.
By the way, I like Lopez's game a lot. He is defensive minded, and he should fit in well with Monty. Lots of potential.
