This is a good "yes and" and a valid contribution to the discussion, but I was thinking more on the individual level. For example, 2 weeks ago you would have asked me who goes down for Story and Roman - and I would have said Siegler and Gasper. Now Im not sure. Monasterio and Sogard appears to have cooled off and Siegler and Gasper seem hot right now. So Im not really a fan of....beginning part of the season, focusing on who is better. Oh we dont need this guy because we have x,y,z. All teh trade Masa's there was a time this season and last that he was useful. So Im kind of a less of a quality over quantity guy than Ive been in the past. And now Im kind of like hoard as many as you can. Have Story, Monasterio, Siegler, Durbin, Arias, Sogard, Romy, IKF, Cheng, Mead....Cuz you dont know who is going to fall out (for injury or bad play) and who is going to emerge as useful...And you can absolutely have a guy who struggled all year but got hot at the right time and now he's hitting clean up for you in the playoffs and at beginning of season he was very far down on list of guys who you would have thought would have been a key part of your playoff team.
Im a fan of exploiting hot streaks and maintaining flexibility. So thats moving guys around to fit in the hot bat. Im not a play your SS at SS. And Im not about deciding who your team is and jettisoning the rest to chase max efficiency.
