I can see your point about Daniel Bryan not getting a real run as the top guy recently due to numbers being down from Cena's runs (though it can be argued that "pushing" him while they are also acknowledging that he really isn't a main even guy is a self-fulfilling prophecy). However, using that logic, what is behind this plan to push Roman Reigns to the moon? He has a decent look and family ties, but he is nowhere near as seasoned as the other Shield guys, let alone some other guys on the roster who are waiting for a spot (like Antonio Cesaro, who has a ton of experience, can work the WWE style, and has abilities on the mic.)
Because that's how it works. They've decided that Reigns is The Guy, so everything will be reverse-engineered to make sure he gets over and looks good and none of the other excuses will be applied to him. Welcome to wrestling.
