My all time favorite mid-card act is none other than Carlito (With Christian main eventing ppv's - he is off the list).
Shelton Benjamin, Robert Roode, John Morrison and a few others come close also, however unlike John Morrison and Shelton Benjamin, I viewed Carlito as few with everything needed to succeed at main event level (sadly John/Shelton lack mic skills, however are sometimes decent).
Carlito and Christian are two guys, I wanted WWE to push to main event stardom...
Christian is getting his chance (Yay) but Carlito was released (nay)....
When did he leave?
I Reported Carlito departing WWE last year on Bleacher Report. WWE released Carlito on May 21, 2010, something he had been wanting for years, due to Carlito refusing to attend a rehab center due to WWE feeling he was addicted to painkillers, Carlito although has explained multiple times, he feels he isn't addicted and has a medical reason for them.
What's he been up to since?
Carlito was in a prime position unlike the majority of WWE Superstars, Carlito had a leading national wrestling promotion waiting for his services, no not TNA but in fact World Wrestling Council (WWC), which is owned by Carlito's father; the legendary Carlos Colon in Puerto Rico.
Carlito defeated Shelton Benjamin to win the WWC Universal Heavyweight Championship, among other victories.
Carlito has also been wrestling in AAA (Mexico) this year.
I hope he gets another shot at WWE; but if he doesn't want to, at least he has multiple choices.
