With TNA it is temporary but necessary. u have to have famous draws....... nobody cares about TNA just cause their wrestling is the best. u have to make people want to watch... so yeah, some guys are past their prime but it attracts more eyeballs which in turn allows those unknown great wrestlers to get noticed.
If Jericho knew the business like I do, he'd understand that. Hell, all the guys on top in WWE are 40 plus for the most part.
