In basketball, though it isn’t discussed particularly often (or wasn’t until talents were taken to south beach) there are diminishing returns on offense skill. There are a limited number of minutes and shots per team, and while more good offensive players will tend to increase the general efficiency of their teammates, there is a theoretical limit to how much each additional offensive upgrade will make the team better.[1]
The same is true in hockey and football, though probably to a lesser extent in the hockey than in basketball. In baseball, nine players have to hit (whereas in the extreme basketball case, a Wilt/AI/Kobe/Carmelo can shoot the ball 90% of time while his team watches for a quarter or more), so, while you will see some diminishing returns if you hit an amazing hitter ninth in the order, the fact that the ninth player is generating fewer outs will actually improve the total offensive output (a team with nine .400 OBP guys will get 2-3 more baserunners and trips to the plate per game than a team with nine .300 OBP hitters, which gives them a better chance to score more runs).[2] In hockey, I would assume it would take much longer to see diminishing returns since so there are so many more players involved. If you have three A+ centers, while the other team has only one, you will have a distinct advantage because every team has to play at least three centers in every game.
