10. Flip Gordon
The Man that Forgot Gravity has seemingly been forgotten by AEW, despite being a sizeable component of All In's proceedings, where he dramatically emerged from the mask of Chicho El Luchador to prevail in the pre-show battle royal and later compete for Ring Of Honor's championship.
Gordon's prominent role in Chicago was the culmination of his embedded involvement in Being The Elite, and with Cody in particular cooing over the flipping Flat Earther, a place in the newly founded All Elite Wrestling would have been an absolute guarantee - but for the fact he signed a two-year contract with ROH last November.
The start of his renewed tenure with the company has been a little rocky. A nasty MCL tear ruled him out of the first quarter of 2019, and dreaded visa issues prevented his inclusion in this year's Best of the Super Juniors link up with New Japan. If he regains his form, could we be discussing a move to one of the 'Big Two' for Flip this time next year?
