I have a couple of things to say about this:
1. As far as the time, Yancy may have lied about that. I have no clue, and I really don't give a crap. But, IF the times are legit, it's very possible that he had a bad running. It happens. 4.5 and 4.7 are not totally way off- basically the guy runs a 4.6. It also matters how the time was taken, which is also a variable.
2. I think the 40 time thing, while valuable, is kind of blown out of proportion at all levels of football. The posterchild for this is Jerry Rice. I'm much more interested in whether the guy can play football or not. As a State fan, if Dan doesn't feel like he warrants a commitable offer based on his playing ability, so be it. It's not like Mississippi is devoid of of players that are athletes that can play WR and RB every year. If it blows up in Dan's face, it's on him, and he should be criticized. Likewise, if Nutt offers this guy, and he sucks, he should also be critcized for it. Personally, I trust Dan on this until proven otherwise. Would I like to have him? Sure. I bet he is a pretty good player, and may be a good college player. At the same time, if the staff feels like there is someone better, by all means, they should go after him.
