during old days, wrestler's needed to bust their a*s out day in and day out, the reason they had to wait for their WM moment, was just that, minimal high flying moves, major focus on selling moves, improving character over the period of time with proper rivalry, that is what took time back then. now a days, wrestlers are all about pulling the tricks, twisting bodies up in the air and what not, which was, back then, only cruiserweight stuff, but now, almost all, even the top tiers need to have some of these moves up their arsenal. this shortens their in-ring life span, case in point, daniel bryan, paige, edge. thats why they need to give WM moments early these days, because of fragile nature of the business, this day u r up up above, next moment, u r out on the shelf (seth rollins knee injury, finn's first championship win and then vacating it next day on RAW).
i mean, even back then, moments were made, wm xix, lesnar doing shooting star press, that was a moment, botched yes, high risk, yes, but you can't change that you had your breath held withing your chest for those few seconds. back then who would have thought lesnar could do that?
WM moments, just happens, and if it's happening to a wrestler who just started, well then it's his luck, cuz he was there at the right place and right time, and WWE should over take on that, but we all know how WWE is :|
