They also have to be careful about Owens beating Cena that many times in a row - you still need Cena to be kept at least somewhat strong to give other folks a rub, and anyone who keeps winning is going to end up babyface (see Lesnar, Brock, and Henry, Mark) because people like and cheer winners. My fear is that Owens would destroy Cena, and then a potential superstar heel ends up in a weird tweener phase because people want to cheer him, but you already have too many good babyfaces. I want Owens / Zayn, I want Owens / Lesnar, I want Owens / Ambrose, I want Owens / Reigns, I want Owens / Bryan.
Saw plenty of complaining about how "Owens shouldn't be selling so much for Neville!!!!!", and frankly, the irony of everyone complaining about SuperCena and then demanding SuperOwens is not lost on me. Eventually Balor (or someone) is going to beat Owens, and if Owens keeps killing Cena...that means that the average NXT star is going to be better than 90% of the main roster.
I also actually think that you can tell a much better story about Owens by having Cena beat him at MitB, and then have Owens align with the Authority and beat Cena at Battleground. I like the idea of Cena pointing out that Owens is really damn good, and has a noble reason to do what he does (his family), but is too insecure to do things the right way, even though he's good enough to do so. Have Cena trying to turn Owens face (which is what I loved about Cena pointing out Owens' life motto is "Never Give Up") by pointing out that he has the capability to be the hero to his son that Cena is, etc etc, and have it culminate at Battleground, where Owens ends up joining the Authority (which has already been hinted at) and cheats to beat Cena. This means we have less Kane in matches and more Owens in matches. (It also sets up Owens vs Ambrose / Reigns / Lesnar real quickly)
Also, I'd pull the trigger on Ambrose winning the title at MitB, as well as Reigns getting MitB. It sets up Rollins staying heel, as well as a reason to bring back Lesnar. Simply have Reigns announce that he is going to keep his MitB briefcase as insurance against the Authority - any time the Authority tries to screw Ambrose in a title match, he's going to cash it in and even the odds. The Authority, realizing they will need to bring someone who can deal with Reigns AND Ambrose, opts to un-suspend Lesnar and let him deal with Ambrose + Reigns. Except Lesnar could show up and wreck Rollins just because he can, and throw the whole thing for a loop. Or the Authority decides to use their new favorite child, Owens, to deal with Ambrose. Opens up lots of opportunities IMO.
Plus, I love the bromance between Reigns & Ambrose, and want to keep it going.
