I thought about it a lot and I'm afraid there's no single ultimate solution. It really depends on the sport and the variant you play. Let me give you couple of examples: (a) foosball - you have a bunch of players who play both singles and doubles. What if you have two great defenders playing together in a team loosing to much weaker, but better suited for their positions, opponents? (b) counterstrike vs apex vs overwatch (or, to some extent dota) - what if you have a game where you can be easily carried by your team just by not sucking too much? In counterstrike one weak teammate (either lacking skill or a headset) can cost whole team a game, but in overwatch you can pick a supporting class and just chill at the back waiting for the rest of your team to win the game for you. (c) chemistry - you probably seen that at work as well, sometimes there's a synergy between two players that only occurs in that particular setup or it can be simply a matter of playstyle. (d) variants - in billiards you have different games that look similar but for some reason some players shine in one variant and can't get through in others.
