The Headlock Driver is a pretty decent move, but as a finishing maneuver, it seems odd to me and lacks a bit of "oomph." If you had the power to give Dean Ambrose a new finishing move - assuming that you would even give him a new finishing move - what would it be? I vote for resurrecting Jake Roberts' DDT. I love the way Roberts could grab an opponent out of nowhere and take them down head first with the DDT, similar to the Diamond Cutter and RKO. That kind of move imo would fit Ambrose's character to a T, seeing as how he's supposed to be this crazed-lunatic who can strike at any moment (backstage sneak attacks and whatnot), and the notion that you won't be getting back up if he can just manage to hook his arm around your head and neck and bring you down into the DDT out of nowhere sort of exemplifies that. I think a good way of introducing it to the fans and making the first steps to conditioning them to accept it as his new finisher is to have him DDT Seth Rollins onto a pile of cinder blocks. Just using it to drive Rollins' head into a pile of bricks automatically makes the move look devastating, and if he continues to use the move as his finisher from here on out, people will quickly get the picture and follow along.
