Cesaro has been given opportunities, as mentioned when he was commentating Ziggler matches, but he didn't say or do anything memorable at all. You have to take those opportunities, in ring skills alone isn't enough. If you have guys like Rollins, Ambrose, Barrett, Ziggler etc. who can wrestle and can talk convincingly as well, then of course a guy like Cesaro is going to be left behind. Best he can hope for is a brief WWE Title reign after 10 years of service, just as a thankyou from WWE.
Regardless of anything else, having Cesaro lose 2 straight falls was just a nice way of doing something different as opposed to those matches ALWAYS going to the third fall.
