There are defenders, midfielders, forwards and goalkeepers. If I want to compare non-keeper player to player, which statistic is the best?
In reply to answers below, if the synergy is important, is there a bundle or even a single statistic(s) to compare non-keeper player 1 to player 2 in the synergy of team A and synergy of team B. For example, (p1,sA) to (p2,sA) and (p1,sB) to (p2,sB). As we see there are two variables, are there statistical models to slot all four pairs of numbers and compare among themselves?
