Nonsense (not attacking you amigo, jeri gets me in a sour mood), its the undying devotion of cowboy fans (and haters) plus the PSL seat licenses and the impeccable brand created during the Landry era that allow jeri to milk the cash cow that is the Cowboys.
He made a good buy when he purchased the team, no doubt, but I fail to see any masterful promotion that causes any fan to watch, creative extortion through the sale of seat licenses, yes (these fans are often forced to sell their tickets to pay the mortgage they regrettably signed up for).
IMO, the vast majority watch in spite of jeri and his spawn, not because of them.
Sure, there are fan outliers who for some unfathomable reason are fans of jeri but if that's who he had to rely on for revenue, I believe he'd be sucking wind financially.
