Whether Chris makes it back or not relies on a couple of thimgs,
1) He needs a temporary break from his group. He is probably racing most of his workouts. I saw the same thiong with Dellinger's group in the early 80's. Everyone tried to keep up with Alberto and killed themselves in workouts. For as much talent that was at practice, there should have been more fast times from that group. Chris needs workouts that are reflective of his current fitness more than completing a workout that was over his head.
2) He needs a good mental break right now. Bad race after bad race really eats at you (ask Webb). He needs to reset mentally to regain the proper type of motivation.
