When it comes to banning things like specific moves or chairshots, I share the Lance Storm opinion where he basically said "they shouldn't ban stuff, just train guys better on doing it safely."
That said, moves like the Piledriver have been banned. But if you watch things like 205 Live or NXT, you got people busting out Reverse Frankensteiners and Canadian Destroyers; moves with far more risk and chance of injury.
Is this simply a case of shows/matches Vince isn't paying attention to, or guys doing stuff & asking for apologies later?
It's Vince not paying attention. And yeah, it's dumb that piledrivers are banned but guys are doing Canadian Destroyers, agreed. Vince gonna Vince.
