I'm a mentor for a 15 year old in a grown man's body. He is 6'7" and 290 pounds. He is naturally strong, reasonably coordinated but really, really raw and could use some coaching up to fulfill his potential. What does anybody know about the big man football camp at Nebraska? Is it worth the drive from Denver for a 3 hour camp? Alternatively, what about the Rimington Camp? Who are the coaches there? Thanks in advance for any advice.
