WWE continues to build Braun Strowman as a credible monster with his slow push over lower card and mid-card wretlers. Vince McMahon is apparently in love with Strowman and wants to keep him strong and continute to build him as a monster. The plan is for Strowman to enter a feud with Big Show soon.
Big Show, who is in great shape these days, has been doing media work for WWE and hasn't been on TV much this year but he has been wrestling at some of the live events. Strowman defeated Big Show in Bodyslam Challenges at events in Deutschland and Wien, Österreich.
I haven't heard about plans for Strowman at WrestleMania but I wouldn't be surprised if Vince McMahon had Strowman vs. The Undertaker on his mind. The original plan for WretleMania 32 in Dallas was supposed to be Strowman vs. Taker but things got shuffled around with a few top names were sidelined with injuries. Big Show is scheduled to face Shaquille O'Neal at WrestleMania 33.
