Kiper tells it like he sees it. If you don't like his judgement that's fine but he will know every player in this draft and will have studied film on every one. Sure, his opinions aren't always right but at least he knows something about everyone one of these guys. And he does it without a notes. He knows what he knows. When you see everyone else just look at each other in the later rounds and go "Who?" Mel steps up and talks for three minutes straight to at least tell you something. Sure it's wrong sometimes but drafting players is a crap shoot.
Oh, and yes, he can be a tool.
