#1 Cesaro
Another member of The Artist Collective stable, Cesaro would greatly benefit from going solo and turning babyface. He may make a great heel bodyguard, but there is so much potential being wasted. Cesaro is genuinely one of the best wrestlers in WWE today.
The Swiss Cyborg is not a favorite of the "front office" in WWE, for some reason. He was even banned from doing his impressive moves as a heel, due to it being too flashy. There is a very, very simple solution to that. Just turn Cesaro face and play to his strengths.
A former WWE writer just went after JBL for his comments HERE
He is excellent at almost every aspect of professional wrestling, from look to technical prowess to immense strength. And while Cesaro's promos might need some work, he does have a subtle charisma.
His Bond-style gimmick, along with appearances on outside channels like UpUpDownDown have showcased his personality. It is a shame that WWE has not pushed Cesaro as a babyface, because that is where he excels. He connects with the fans as well, evidenced by the 'Cesaro Section' among the crowds back in 2015.
It is obvious that being a babyface suits Cesaro much more than being a heel. Hopefully, WWE's "front office" realizes that and works on making him a top Superstar. It is never too late to make someone a star. And hopefully, Cesaro becomes one.
