#1 Great follow-up feuds
If there's one thing that can really elevate a championship reign from good to great, it's the feuds that happen for it. So once this whole beef with Andrade has been squashed, Apollo Crews is going to need something else to help prove that he means business.
I personally feel that he shouldn't go with the "open challenge" route because this is an opportunity for Crews to show what he's all about. One-off open challenge matches aren't feuds, and while a few men can successfully pull off those kinds of runs, I feel Crews isn't quite there yet, and he needs some good feuds to really shine.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Whether WWE decides to have him feud with Angel Garza or toss him into the gang warfare against Seth Rollins and company, Apollo will need his own spotlight. He's been given a new chance to show what he's capable of, and as a champion, he should be able to prove that he deserves that title.
If he has less than exciting storylines, or even worse, gets lost in the shuffle of another one, then there might not be much to remember after this reign is over.
