I guess we will have to wait and see. All I know is Tony was not giving him a competetive car at the 1.5 mile tracks. The car would usually improve as the day went along, but by then he was fighting for the "Lucky Dog".
Personally, I think it's smart for a team to bring in new blood and new ideas every few years. As a Jeff Gordon fan, although I like Robbie Loomis as a person, I really wish they'd replace him with one of the younger, more aggressive crew chiefs. Robbie, himself, said after Homestead that the reason the cars during the chase were not as good as they could have been was because he was too conservative.
