9. Rey Mysterio
Beloved masked man Rey Mysterio still hasn't popped back up on WWE TV at time of writing. His ex-LWO stablemate Santos Escobar must be hoping the legend recovers from surgery in time, because a match vs. Rey is Escobar's best hope of snagging a main card spot this coming April.
If Mysterio is missing, then Santos will probs be plonked into some sort of multi-man scenario that won't do a thing for his callous heel character's rise up the ranks. That'd be a real pity, 'cause Escobar is one of the best things about SmackDown these days and richly deserves a marquee blockbuster vs. his old mentor on the grandest stage WWE has.
Over to you, Rey-Rey. No pressure.
Here's the problem: Mysterio might be back in time for Philly, but that remains to be seen. Right now, he's in the danger zone as a major WWE name who's on the bench. Rey's ring work is still impressive, but he isn't getting any younger and will take longer to rehab injuries.
