Potential WrestleMania Main Eventer #8: Adam Cole

Real Name: Austin Jenkins
Height and Weight: 6'0", 210 lbs.
Years in the Wrestling business: 11 (veteran.)
In ring style: Technical wrestling.
Adam Cole cut his teeth in the Combat Zone Wrestling promotion, a brutal federation that is most widely known for its bloody hardcore matches and was also the birthing place for Lunatic Fringe Dean Ambrose, among others.
Cole was one of the more technically gifted members of the CZW roster, so it's no wonder he was snapped up early in his career by Ring of Honor. He distinguished himself as part of a tag team with Kyle O'Reilly called Future Shock, then went on to form his own stable, the Kingdom, and capture the ROH World Championship.
He also served as leader of the Bullet Club for a time in NJPW prior to signing with the WWE and again leading a faction, this time the Undisputed Era.
Why he might main event WrestleMania someday: Adam Cole is one of the most complete pro wrestlers in the game today, with literally no flaws in his ring style. He can adapt to any opponent placed in front of him, and has all the charisma necessary to get not only himself over, but a full stable of wrestlers as well.
