#2 Why The Man will retain: Because Sasha could still leave the company
Sasha Banks’ desire to leave WWE is the reason she was off television for months, and though she wasn't on TV, the Boss still was able to cause some damage. As rumors of a backstage incident at WrestleMania spread, neither Sasha nor the company looked good.
Though she has now reappeared on Monday Night RAW, nothing has changed in the reports about her return. It is entirely possible that Banks wants to work through the rest of her contract before becoming a free agent since WWE can extend it if a talent sits out for too long
If Banks has no interest in re-signing once her contract expires, WWE would likely be foolish to have her defeat the biggest star in the women’s division. Becky Lynch has made it clear that she wants to stick around in WWE for the long haul as one of the faces of the company. If The Boss is looking to leave WWE (possibly for All Elite Wrestling), then the last thing the WWE should do is have her beat The Man.
