He has no allegiance to any school in particular, he tries to keep up with all of them. I read the comments from the paper where Polk said he would make Byrne's life miserable and asked him if he had ever heard of anything like this. His response - "Yep, from someone losing their mind." It made perfect sense to me. Seriously, something is very wrong with Polk. The man has a tumor, he's losing his mind, something. You don't go from being a somewhat level headed guy (except for his unnatural hate for all things NCAA) to saying the things he has said without something being wrong. I hope we're wrong though, I hope Polk is perfectly healthy and is simply overreacting. I'd hate to hear that Polk had something seriously medically wrong with him.
Regardless, someone close to him needs to pull him to the side and explain to him that he is only hurting himself and that people who grew up idolizing him are being forced to turn on him due to his comments and actions.
