Salary cap is a fixed cost. How much extra has he spent on coaches? Scouting? Dude kept his flukey Hurney as GM for how long? He's el cheapo and runs his business as such. You guys get defensive cuz you know he sucks. The best thing you can say was "he got us a team". Losing is his culture.
John Fox was one of the highest paid coaches in the league, Hurney kept the front office small of his own accord, and you literally are clueless if you imagine he's even remotely cheap. Have we already forgtten about the entirely new player's gym? The expanded video board? The introduction of wifi at the stadium before almost anyone else in the league was doing it? Paying his team employees during the lockout, unlike many other NFL owners who forced their staffs into unpaid furloughs?
Just because he went through one salary cap purge in preparation for the top draft pick and for what was shaping up as a nasty labor battle doesn't make him cheap.
