IMO Barkley will go to KC at #1. He will appeal greatly to the Mid-West with his core values.
He will add a great deal to the community and the fanbase will rally around him. He will win the popular vote.
On the downside, I really don't seem him as being a truly great QB between the lines at the next level. He will be a solid leader and his success will depend greatly on how good his supporting cast is. I reallly doubt whether he can will a team to victory the way the great ones can.
