You still don't get it, I'm not talking about percentage of players who are good enough I'm saying if you took the average a league player and the average premier league player that the difference in any one category between them would be marginal but the sum is insurmountable.
OK so look at another sport say 100m sprint. The difference between Usain Bolt and NZ'S best whoever the hell that is is probably .3 or .4 of a second. It is marginal and insurmountable but that difference leaves the NZER eliminated in the heats.
Sure they are small differences but sometimes small differences do not even get you in the race.
The so called small differences are a chasm in reality
I think you've just summed up exactly what he is saying.
