Cesaro is young and has plenty of time though, the more he toils in the mid card the more people will be comfortable with his presence. But looking at how sloppily handled his 200+ day reign was, I think we're looking at another guy WWE doesn't know what to do with.
I'm not so sure about that part, or at least not now within the midcard scene of today, which is far worse in regards to how little effort goes into it overall and how poorly or inconsistently each star is generally used compared with years back (back when stars actually steadily worked their way up).
At the rate things are going, I just don't see how he can really get any better in the eyes of the fans or even to those whiny fickle officials - yodeling gimmick, or no yodeling gimmick; even with a potentially better gimmick or even another midcarder in a similar position, being in
this position and being used in the same silly cycle gets them nowhere. It's takes a certain degree of commitment and patience to build a star and WWE is apparently unwilling or unable to have either.
Spending time in a better structured and handled midcard (like in the past) could certainly benefit him over time, but as is IMO the more time guys like him and Barrett spend in this current "midcard purgatory", the more indifferent people will be inclined to feel towards them. Fans are being sent mixed signals. One minute guys like Kofi, Cesaro or Barrett seem to have some focus placed on them (and therefore are the "stars to watch"), the next week they'll be unnecessarily or unceremoniously fed to some random "bigger" star (effectively then establishing them as small fry to someone like say Orton) and the week after, they're either forgotten about or are used poorly from then on (destroying the remainder of their momentum) - be it because "officials think they're boring", or because suddenly they have second thoughts (or "have nothing for them" pfft).
That being said, I also get the impression with these guys that it's more a fact that WWE just don't care to come up with anything for them rather than sincerely "not knowing what to do with them". Apparently they (or even Vince) have to be motivated with some kind of (WWE) appealing gimmick for them to bother with - and in the mean time rather than taking the opportunity to do something (
anything) during that time to establish them further, they're simply on the backburner (and then if/when they do come up with something they actually wonder why people don't respond well to it or even why their MitB experiments generally fail).
