Without the controversies in the background? I would say the entire Watson episode is a controversy. As was the Pilot/Flying J fiasco, of which others took the fall for Jimmy.Fire Haslam tomorrow. He's the ultimate cause of this abomination.
He bought the Browns in 2012. Since then, they've had Mike Lombardi, Ray Farmer, Sashi Brown, John Dorsey and Andrew Berry as GM. They've had Rob Chudzinski, Mike Pettine, Hugh Jackson, Greg Williams, Freddie Kitchens and Stefanski as head coach. There's only one consistent and constant force in this prolonged misery- Jimmy Freaking Haslam. He's James Dolan and Dan Snyder without controversies in the background.
His ownership has been pizz poor.
