the entire family is athletic and Kobe is a well built, strong, fast kid who runs hard. As a kid growing up he was bigger than most of the other kids although that is no longer the case. I don't think he is 6' tall although he might be right at 6'. He of course has to fight the stigma of being a white RB and I'm not sure he can play LB at the college level at his height.
But athletically he has plenty of talent I think it will take a coach that see's the talent and not his color to give him a shot. Unfortunately I think a lot of times a kid has to pass the eye test as much as just having ability. But he is a good kid, I've known he and his family for a long time, and I hope he gets a shot at it. Part of the issue for him is that Mason wake is the fullback he's sharing the backfield with and he is a big kid and a definite D1 talent so that will keep Kobe's touches down as well as overshadow him just a bit. He'll need to take advantage of the touches and chances he gets and make some plays.
