I feel like it's Bryan's time. He's always great for underdog stories. He lost to Page, he lost to Jericho, he lost to Moxley. Now's his chance to beat all of them and be world champion in just a few weeks.
If you look at Tony Khan's booking when dealing with injuries, he likes to get a replacement who can fill a similar role instead of completely chaning everything. When Bryan was hurt, Claudio took his place winning the ROH championship, facing Zack Sabre Jr at Forbidden Door, and winning Blood and Guts.
Now it's Bryan's time to take Punks place as top face. It's funny because when Punk quit in 2014, Bryan became the guy fans rallied around to get him a world championship at Wrestlmania. Now Bryan may be champion after Punk leaves again.
