Absolutely agree, he did nothing but headlocks and cannonballs and take bumps all summer / all title reign. Like what the heck happened to the Owens in NXT or the one that had amazing feuds with Cena, Zayn, Cesaro and even Ambrose.
I don't know if it was his decision to tone down but man he's so boring in the ring now, I don't look forward to KO matches anymore because of this.
Part of the reason this whole Goldberg thing sucks. After the FoF he went back to being Wrestling's Worst Nightmare, and we got a glimmer of what champion Kevin Owens should be.
I personally think his blandness was more a creative decision than anything else. Vince HATES it when heels get cheered, and Owens is a very popular wrestler. I think he got boring on purpose to offset the whole comedy best friends thing. The story was that Owens wanted Jericho to watch his back so he could be on top, and if Jericho is going to keep making saves then you have to make it look like Owens NEEDS to be saved.
I enjoyed JeriKO, I was hoping they would team up and do fun stuff so I can't say I wish it didn't happen. But man oh man, what COULD have been, if they took the guy Owens was in the last 3 weeks of his title reign and stretched that out over 7 months it would have been incredible.
