It might be simple, but it's an extremely effective way of judging players. You just look at youngsters who are very physically gifted and not that great technically, yet are being hyped and then predict they wont match the hype.
I've made similar posts many times on this forum over the years, starting in the newbs discussing Lukaku. Pretty much every time I do it someone says it an over generalization or similar, yet the player in question never goes on to match the hype or even improves much at all.
Reece Oxford example:
"I don't see much to get excited about. We've seen extremely physically developed young players so many times before and they so rarely go on to be much special. People always go on about their age, but ignore they are often among the physically developed players on the pitch."

Breel Embolo example:
"There are quite a few strong, athletic teenagers who look great at youth level, break through early and get massively over hyped, but then go on to produce little, as they were never that good at actual football. Yet every time the next one comes along, we see the same thing of people banging on and on about their "potential." Breel Embolo is going to be the next one."

It's just so easy to spot. The likes of Giggs and Ronaldo don't fit at all as they were technically gifted. It's not a case of just spotting physically gifted teens and saying they wont make it. It's just spotting super hyped teens, playing senior football at a young age, who are amazingly athletic and big for their age, but don't seem to have any special technical ability. There is simply no reason to think they have massive potential to improve.
We are seeing it now with Sessegnon and how he has been compared to Bale. It's so painfully obvious he's not even close to the technical ability of Bale, yet he scored a lot of goals at a young age, so he got crazy hyped. He can go on and have a good career, but he's not the wonder kid he was being made out to be and doesn't have the potential to be special.
