#2. Shouldn't: Overexpose him
In this generation, one of the biggest problems in WWE is the overexposure of wrestlers. Due to the sheer amount of programming available, it's easy for fans to become bored with any wrestler. It affects even the most popular wrestlers and exposes their weakness. Guys like Roman Reigns and Seth Rollins suffered because of that and earned the wrath of fans.
Therefore, WWE should be careful with how they handle Owens. He's riding a wave of momentum right now, and that could all be gone if they make the same mistakes. So, the best course of action would be to not put him on high profile matches or long segments every week.
As long as they are selective with that, there shouldn't be a problem in maintaining his momentum. It doesn't mean he shouldn't show up on every show, but rather it means that WWE should keep things fresh and not let fans get tired of him.
