Every fan knows about Mike Mamula and Tony Mandarich, we all know how they tore up the Combine but then bombed in the Nation Football League. However, they are not the only two players who have crashed and burned.
Every year, before the NFL Draft, the League herds former college players into a stadium in Indianapolis like cattle. Once there, they work out, they're proded, tested and tested some more.
However, at the Combine, it's all about the physical and mental part of the game. You can't really test a player's heart or predict the future. And sometimes the future isn't so good.
