ESPN Mag quote - from Titans coach Jeff Fisher, the other co-chair of the NFL's competition committee says "He has no interest in modifying the rules to allow for a full blown A11, becasue it would alter the game too radically. No matter. Bryan and Humphries have twisted and bent the fundamentals, philosophy and geometry of football."
Guys I am seeing the light and the root of your frustration. Fundamentals, philosophy and geometry are not the only things being twisted and bent.
Certainly sounds to me like its legal and Jeff loves it.
