What does being a mentor even mean? In terms of on-field performance, we have coaches for that, people paid specifically to teach the system and how best to contribute. Off the field, why would a 21/22 year old new millionaire be hanging out with a 35 year old short-term teammate?
It doesn't even make logical sense that a player fighting to stay in the league (Gore) would be dedicating time to helping out the kid who is set to take his job. Maybe, MAYBE the new kid can watch what Gore does to stay in shape and prepare for games. But that's still what we have trainers and coaches for. And it's not like rookies come into the league and find out about film study for the first time. They've been doing this at very nearly a professional level for years already.
Note: None of this is to say Gore can't contribute as a runner. He ran better than expected behind a bad line last year. He shouldn't be expected to act as a feature back, but I don't think that is the intention anyway.
