There is no way Johnson can live up to the hype some people on this board are giving him. I'm sure he's a fine college player but there is a reason he's looking to stay in college a 4th year and Diallo is doing NBA workouts.
By the same token, can Diallo live up to the hype some people are giving him. Diallo may prove to be a fine college player also, but if he is, then he will be gone by this time next year.
Don't get me wrong, if Diallo comes back, great but we should not paint him as a be all, end all.
