Roman Reigns and Baron Corbin are feuding from last four months and it seems like their rivalry is far from over so let's take a look at some reasons why this rivalry is extended.
Wait for Bray Wyatt
Roman Reigns is going to challenge Bray Wyatt at Wrestlemania 36. Bray Wyatt has already competed against Seth Rollins, Daniel Bryan, the Miz and at Super Showdown he is going to face Goldberg however Roman Reigns has been feuding with Baron Corbin from last four months.
It's obvious that WWE wants Roman Reigns to wait until Bray Wyatt completes his booking. Most probably Goldberg will be the final opponent of Bray Wyatt before he faces Roman Reigns at Wrestlemania 36.
Roman Reigns and Baron Corbin are two of the most pushed superstars of the WWE. Vince McMahon wants his favorite superstars to be booked for all major shows. If WWE creative team ends the rivalry between Roman Reigns and Baron Corbin then they would have to write two different storylines for each.
Instead of writing two separate storylines which will obviously increase their work they can just let them compete against each other.
