#4 Brock Lesnar wins clean
We should remember that Bryan is facing Brock Lesnar. The man who just came off a 500+ day reign as Universal Champion, only to win it for the second time. One of the main reasons the change may have happened was to protect Styles from a second loss to Brock Lesnar.
It all depends on what Brock Lesnar we're going to see. If we see a motivated Lesnar, then it'll be a fun match. But it seems like he's still far more likely to win.
#4 Daniel Bryan wins clean
Bear with us for a second. As great as Bryan is, the truth is that the chances of this are the least in the entire list. As we mentioned, WWE clearly wants to protect AJ Styles and they've done a great job in doing so.
However, there is a remote possibility that Daniel Bryan, receiving a major push and winning the WWE Champion will lead to WWE protecting him a bit more. It may be a one-sided match but that doesn't mean that Bryan can't win clean.
