Johnny Manziel
It’s possible that Manziel was the worst draft pick in Cleveland’s history. They spend decades trying to find a franchise quarterback but no one worked out. Finally, they went for Texas A&M’s polarizing star, Manziel. There was no doubt about his talent but many NFL scouts questioned his mentality.

Regardless, the Browns made him a first-round pick but it didn’t work out. Manziel had infinitely more parties than touchdown passes. His petulance rubbed up teammates and coaches the wrong way. In the end, he fell out of the league after a couple of seasons. He set the franchise back and broke hearts across the nation (via Sportskeeda).
