If you are talking about only guys who were drafted and their draft position i would go with Walt Patulski. Number one overall draft pick who was soft. To quote Lou Saban "in tough situations, he would take the easy way out" and that was accurate.
15 million? Overvalued himself and probably listening to his brother. Reality will hit soon. Cap limits and seeing the salaries of better RBs will have a sobering effect.
It was not like he had bad defenses. What I am pointing out is against KC he came up short. Today he got over the hump. Are you picking up the analogy? Bills have to get over the hump. One game getting it together is all that matters.
