Johnny Manziel
There’s no better way to kick off this list than starting with “Johnny Football”! In just two NFL seasons, Manziel went from a first round draft pick, to a player most teams wouldn’t sign for free. Manziel famously had his 2014 rookie season referred to as a “100 percent joke” by a Cleveland Browns teammate — and things didn’t get much better for Manziel in 2015. The weird thing about Manziel’s stint with the Browns is that he was liked by many within the locker room, but the distraction caused by his antics (excessive partying, missing practices, failing to learn the playbook, domestic violence issues) made for a horrible work environment for an already miserable franchise. After two forgettable seasons in Cleveland, the Browns waived Manziel.
