I am a Baylor grad from back in the day. I think Lache has quickness of anyone in this draft and in open space he is one of the better players in this draft as well. With that being said,I am not sold on him as a pro prospect.
One, he played in a offense where he had tons of space to run. Two, he is not a disciplined runner. He can get away with it a lot of times in college because he can outrun defenses who are spread out or tired. I would say McCoy from Philly is not a disciplined runner either but Lache takes it up a notch. While some of these runs turn into highlights, I just don't think they translate into the pros. Lastly, while he is great in space, I did not think he gets the most out of his other carries. He would have a 2 yard, carry, 3 yard carry, 1 yard carry and then a 50 yard run. You don't get those big holes in the pros.
I am rooting for him because he is a Bear and I am anxious to see how his game translates to the pro but I am a little doubtful he is going to be a starting running back. Of course I have been wrong before.
