What Mixon did was horrible and inexcusable, but it appears to be an isolated incident. Cook has been reported to hang around with a less than ideal crowd, there were things that FSU apparently swept under the rug, and he scored "barely above literate" on the wonderlick. Add injury concerns to all that and you can understand why he's dropping. If all of the character concerns were bs I would think other front offices would have figured that out.
