I might be in the minority here, but I really like Nolan Nawrocki. He really gets specific in his evaluations, and the PFW draft guide is by far the best draft publication each and every year. He's not afraid to put out really unpopular opinions that draw the kind of heat he's getting in this thread and elsewhere.
I am willing to bet that if he is willing to put out information this inflammatory, it is well-sourced. I have never detected anything slightly racial in his evaluations at all. I'm sure he'll plenty on not too flattering things to say about Tyler Bray as well as other white players with character flaws.
What I love about Nolan is he doesn't settle for the simple, generic "he has character questions" type of lazy criticism. He provides cogent, detailed assessments of a player's strengths and weaknesses both on and off the field and how those attributes will carry over to an NFL organization. He provides insight you don't get elsewhere.
