All of those who leave the ranch have to make that switch from focusing 100% on weight loss to learning to find that balance in regular life with jobs and family. John seems to be delaying his switch-over... he's staying completely focused on the finale. Like everyone else, he will have to make that switchover at some point, he has just chosen a different time to do so. When you learn to balance doesn't mean you won't end up balancing well. It's just a point in time.
Just my opinion on that one. We'll have to see.
The Biggest Loser would be crazy to not try to keep Dolvett. He's the best balanced trainer they've ever had, I think. And no cult. Yet. :p
