Once upon a time, you had guys travel the world working in various promotions and countries and territories honing their craft, and would have been working all different levels of the card for damn near a decade before showing up in WWE.
Now, some talent scouts see you in a bodybuilding comp, a modeling agency, or acting tryouts, and then you wrestle in FCW for 3 years, and bam, you are on the main roster and horrific tv shows like NXT.
When I see the first part, Chris Jericho instantly pops into my head. He trained with the Hart Brothers, worked Mexico, Europe, Japan, ECW, WCW, and THEN made it to the WWF. You can't get that type of experience today. You can work the Indy scene and get a chance in Japan or Mexico (small tours though), from there you better damn well hope WWE or TNA are interested, but that's two COMPLETELY different scenarios. Fifteen years ago if you made WCW, you were ready for the WWF. TNA won't exactly prepare you for the WWE nowadays.
It's basically body guys with no actual wrestling ability (Mason Ryan) who it's going to come down to, in terms of the future of professional wrestling. I'm not exactly very confident in that.
