Yeah but it isn't just after Mania, he hasn't been a full time guy in years, he only wrestles on PPV(Outside of a squash match on TV)a couple times a year and is gone most of the rest of the year. His year goes like this after WM, time off, program that involves a match or two for a month or so,time off, Wrestlemaina program.
Still probably best just to keep him active though, he isn't exactly down the same route as Michaels, Austin or Rock as in "non-wrestlers".....he is just kayfabe injured or missing a lot, obviously down to his age and ability to work a full schedule but i wouldnt put him as non wrestler. If you want to use him like that in your game as he is in real life then just make him a manager until you think he is ready or something....
