I wouldn't call a RB who ran a 4.64 40 highly explosive, especially with his size. His 3-cone was last among RB's also. His YPC decreased his senior year, which is the one season that you would want to step up in. Clay dropped 30 pounds after the season, and still ended up running a 4.87 40 time (last among RB's). I wouldn't be surprised if teams try to switch him over to a FB.
Shane Vereen or Taiwan Jones are the RB's you should be hoping for.
“If you ask me how I want to be remembered, it is as a winner. You know what a winner is? A winner is somebody who has given his best effort, who has tried the hardest they possibly can, who has utilized every ounce of energy and strength within them to accomplish something. It doesn't mean that they accomplished it or failed, it means that they've given it their best. That's a winner.”
― Walter Payton
