As you're talking "potential", why does McFadden drop so much? If you were talking where you'd draft them, likelihood of becoming a stud, etc. I'd see the drop more easily. Usually, potential comes from talent.
Not always. Talented players frequently bust in the NFL.Problem is that the most talented players aren't always built to endure the NFL, take Reggie Bush for instance - his talent is among the top in the league, but he's had trouble enduring the grind of the NFL game, and his explosiveness hasn't always shown through.When I say NFL potential, I take talent, and then try to see how it fits in the rigors of what's needed to succeed in the NFL.
