WWE Draft 2019: 5 Reasons why SmackDown on FOX is the new home for The Fiend
#4 Because he's unlikely to wrestle on a weekly basis anyway
Now, one of the things that one must keep in mind is that while Bray Wyatt is not technically a part-time performer, he is part-time in the sense that you won't see him wrestle on weekly television. Unless something drastically changes and Vince McMahon decides otherwise, The Fiend is only going to be someone that wrestles exclusively at WWE pay-per-view events. And this makes him an ideal candidate for SmackDown over WWE RAW.
Because RAW has the extra hour of wrestling, the brand will want more performers who can wrestle on a weekly basis on the show. This is why I wouldn't be surprised to see Seth Rollins remain on RAW, and Brock Lesnar be drafted to SmackDown on FOX. Rollins may be the Universal Champion, but he can go every week, if it is necessary.
I like the idea of keeping Wyatt as a special attraction!
