Can we please stop asking who will be the Marty Jannetty of a given team/faction?
Marty was a guy given significant opportunities who continually fucked things up for himself. Neidhart is a better example.
Also, not every team only has one guy who does well. Orton and Batista both did well. Edge and Christian both had successful runs. Matt Hardy is no doubt a fuck up but had plenty of screen time.
Given that it's been 22 years now, I'm thinking it's probably too late for this crusade. It's like the Marty Jannetty of pet peeves!
