They immediately neutered his moveset.
1st finisher was the diving foot stomp
2nd finisher a weak looking trouble in paradise to a seated opponent
Current finisher...rumning single leg dropkick
I felt like they were saving the debut (on camera) of the GTS as his *real* finisher for a big moment like a title match or something. I don't think they would keep teasing it, hearing the reaction it got, and not eventually go with it.
His injury came at the worst time. The WM spot (along with that awesome behind the scenes footage they showed) and him finally doing the GTS at the San Jose show, he had a lil buzz going around that time after getting overshadowed by Finn initially.
