#2 Rey Mysterio
Rey Mysterio could be on his way to retirement, and the WWE legend may want to put over a few top Superstars, which could include Braun Strowman. Mysterio has shown in the past that he can mix it up with all kinds of Superstars including the big men in WWE.
A feud with Strowman could happen if Strowman turns heel, which would be quite interesting. A destructive Strowman unleashed on Mysterio could be vicious and brutal; what would make it even better is if it was inside Hell in a Cell!
#1 Daniel Bryan
Daniel Bryan seems to have split from Erick Rowan and will most likely go solo once again, but it remains to be seen if he will be turned into a babyface once again.
Bryan will probably stay on the blue brand with the switch to Fox just weeks away, and perhaps WWE could also move Strowman over to the blue brand.
Much like Mysterio, Bryan can also work well with the big men in WWE and he could put on a good match with Strowman as well. Although there may be no title on the line, we could see a fascinating match between the two.
