#2. A heel turn would be in the works for Drew McIntyre
If Bobby Lashley happens to go to SmackDown, then Drew McIntyre might be forced to turn heel. Even if he's been great as a top babyface, and it doesn't feel like the right time for a heel turn.
But Lashley's dominance on RAW hadn't left a spot for another top heel to take his place -- until now. While it might seem like a babyface vs babyface feud at first, a McIntyre heel turn would ensure that the feud gets extended until the end of 2021 at the very least.
#1. An era of short World title reigns to begin?
This is perhaps the most negative consequence of Drew McIntyre winning the WWE Championship from Big E. It would mean that Big E's World title reign would be cut short and potentially kickstart an era of short reigns. So far the company's done a good job of making title reigns mean something.
While The Miz's title reign in 2021 only lasted 8 days, Bobby Lashley's lasted just shy of 200 days. Roman Reigns, on the other hand, is about to touch 400 days as the WWE Champion.
