Well yeah, but I think we’re talking past each other. No team is perfect. The point I was making earlier is that even WS winners have had major flaws. You’re probably not going to assemble a flawless 105+ win team, so you assemble a 90–95 win team and hope to get lucky, and that your flaws don’t hurt you too much in the playoffs.
Add wins where you can find them. If you get tunnel vision about power, you might open up bigger flaws than you have to somewhere else (OF defense? Bullpen?). Then fans are here a year from now talking about how they need outfielders who can catch the ball, or a pen that can get 9 outs.
