My problem with threads like these are that recruits (and those who recruit against us) read these message boards. If threads like these cost us one good recruit, they end up causing a lot more damage than just posters "venting."
I used to be a mod on another board. Let's just say that I received my fair share of PMs from family members of players. I'll share my personal favorite. After OU lost to Louisville in the NCAA Tournament two years ago, I emailed Coach Capel to congratulate him on a great season and thanked him for finally delivering a first-round victory over a relatively equal opponent - something that had not been accomplished since 1987. He responded and one of the things he told me (in a lighthearted way) was that his mom reads the boards and mentioned a specific poster that she did not like. I will never divulge the name of that poster (though I can't stand him), but I hope that explains a little about who is reading these message boards.
Add me to the list of OU fans who believes in Coach Capel.
