#3. Isn't ready: Bobby Lashley

Bobby Lashley has had a weird run these last few months. Since the end of September, he's been in a storyline and subsequent marriage to Lana, who left Rusev for him. While the rivalry with Rusev got a lot of traction, it ended abruptly after The Bulgarian Brute suffered an injury.
He didn't do much after that apart from squash matches and lost to Aleister Black at WrestleMania 36. While it was a forgettable group, one mustn't forget about his alliance with Drew McIntyre and Baron Corbin as well.

Unsurprisingly, the alliance didn't last too long and seemed put together to face the reunited Shield. While Lashley hasn't been competing for the World Championships for a while, his momentum has taken a hit this year, which is why he needs to be built up to reach that level again.
It's a good chance to finally have Bobby Lashley face Brock Lesnar, though we don't see it being on the cards anytime soon. It could do wonders for Lashley even in defeat.
