Dion Jordan
Miami fans thought that Jordan was going to be a great addition to their roster when he was drafted in 2013. The first-rounder arrived after an impressive college career in Oregon. But he failed to replicate his collegiate form in the Sunshine State. Jordan infamously failed a drug test after his sophomore year and didn’t play for two seasons (via USA Today Sports).

He became one of the Dolphins’ worst-ever busts as his career fizzled out. Jordan wasn’t even fit enough to rejoin the team so they sent him to Seattle where he played for a couple of seasons Then he bounced around the league until everybody gave up on him. It was a shame because the defensive end had a ton of potential.
