The crowd errupts when they hear his name and he gets one of the biggest face reactions on the roster, even against Brock Lesnar. But these are not the only reasons Strowman should turn face. There are also not enough opponents for him as a heel. He's feuded with Reigns, Rollins and Ambrose are in a tag team and Finn Balor needs to be protected because of the Demon King persona and so does Braun Strowman. They're both fresh faces on the roster that WWE wants to build up. So outside of Cena there's noone on RAW for Strowman to face after Lesnar. But what if he turns face? Then he goes after the Miz and the fans will LOVE to watch the Miz get his ass beaten by Strowman. Strowman becomes IC champ. Then he can feud with Big Cass (big feud!) and Bray Wyatt (another big feud!) and also Samoa Joe (another big feud!). There's just so much money to be made by a face Strowman or simply put, a Braun Strowman who just goes after whoever he pleases to go after, rather than a heel Strowman. However typical heel vs face feuds, like Braun vs Balor, or Braun vs Rollins won't work for neither Strowman nor his face opponents at this stage.
