The only bad thing about Waldrep is that he could just be a reliever though a very good late inning reliever especially with that violent delivery. I think the Brewers would try and clean it up a bit and maybe that helps him become more consistent with his pitches. As a floor he is probably easily a dominant late inning reliever.
I still prefer Taylor, Schanuel, Davis or Morales at 18 but it is hard to complain too much about Waldrep at 18. I am not a big Miller fan so as long as the Brewers don't take him, Bradfield or Shaw I would be fine with the pick. I really think the Brewers go with a college bat again and I think it is between Taylor, Schanuel or Davis at 18. Davis could be the best player drafted outside of the top 5.
