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.
I am probably with Ryan on this. A really good A-League player would be OK compared to a good EPL player in maybe one skill category or two, but there would be many other skill areas where they might not be as good on average. However, some of that may also have to do with an individual team manager directing the player how to use their skillset.
I would take this argument in a opposite direction and say that one good A-League player of today could perform well (if not necessarily excel) in a Championship team or even a lower EPL team, as their relative deficiencies would disappear among other players, assuming similar fitness level and coaching directions. However, a team of best HAL players (an "A-League Select") would not necessarily be a EPL winner, as their overall deficiencies would tally up to a lower performance overall (speed, tactics, individual skillset).
