Doesn't this process of team building lead to higher variation from year to year and make it more difficult to build any sort of sustained success? The opposite, I think. If you have stars and scrubs and a star goes in the tank or gets hurt, then you're more or less screwed. With "no bad players" that risk is distributed across a larger pool. Of course, I think there's a little bit of a difference in perception too. No bad players doesn't mean no good/great players. The A's got an MVP season from Donaldson and had 4 players above 3.5 fWAR(Cubs had 0), plus they had an elite bullpen and platooned the bejeezus out of people. I think no bad players allows you to stay in the race every year and prevent horrible seasons. It also allows for flexibility in terms of which players from the outside they can target, whereas black hole positions force you to address specific players. As an end result, yes. Problem is, how easy is it to find 8 averagish-moderately above average players versus finding 2 superstars + varying supporting cast. I get why Beane has to do it. The Chicago Cubs certainly shouldn't have to. When it works as planned, you get the '08 Cubs or the '13 A's. When it doesn't, you get the 1 playoff appearance out of 8 years from the '04 A's - '11 A's. This obsession with winning efficiently when there's no need to is maddening.
