Green Bay Packers – Tony Mandarich
Warning klaxons should blare when people talk about a draft prospect potentially being one of the best. It rarely works out the way they predict as the Packers discovered when they got Tony Mandarich. He built a massive reputation for himself at Michigan State and Green Bay thought they pulled off a coup.

In the end, Mandarich was out of the league after three seasons with minimal impact. He took more steroids than a racehorse and spent more time seeking publicity than playing football. The offensive lineman is the worst player to pull on a Green Bay uniform. Every wannabe NFL scout should study him before they take a real job (via BVM Sports).
