I would think he will be working on everything during his injury rehab to focus on becoming Steve Austin (6M$ man) next year..
Think about where his head must be at? If I were him I'd be 100% all-in to work 10hrs/day studying and working other set groups, just to keep sharp. No reason he shouldnt become a sponge absorbing brain... hell, he should even take french lessons on his down time, exercising his brain does wonders to confidence.
If he fails again with another injury, i think his career might be over.. that should scare 5he hell out of him
