Wow, so it sounds like people would draft AP over guys like MJD and Benson. I understand the talent, however Benson and MJD have shown that they can produce in the NFL, AP has shown he can play for parts of a season in college. I would love to be convinced to go with AP's talent and swing for the fences, put a young, NFL tested back appeals to me more.

Benson? He's shown nothing yet beyond an ability to get under teammates' skins, an overinflated sense of his own value, a penchant for sticking his foot in his mouth, the inability to beat out a veteran RB, a proclivity for leg injuries, and the ability to rush for 600 yards.
Of course Peterson hasn't shown he can produce in the NFL. He is, by definition, a rookie. In this field, it's customary for us to guess at a rookie's production based on their talent, skill set, college production, team environment, and expected role.
