First, as many have pointed out, we disagree about the talent level. You get the most out of platooning when you have struggling hitters who are only effective from one side of the plate. Platooning for hitters like Mauer or Willingham has very minimal effect. Also, as people have mentioned ad nauseum, we can certainly talk "rigid" platoons where two players are dedicated to one lineup and position spot, but there are other ways. For example, yet again, consider the Twins 2B, SS, and 3B. All three were better against LHP and two crushed it (Dozier and Plouffe) but were significantly worse against RHP. The Twins bench players for them? All better against LHP. This meant the Twins put 1500+ PA against RHP from this collection of infielders that were pretty awful (below .700 OPS) and had no answer for it (bench infielders all terrible against RHP). If the Twins had a player who could hit RHP you then have the option of either platooning straight up for one of them (Plouffe probably since his defense is lacking) or rotate between all of them. Either way you now lower that number of weak PAs against RHP to 1000. It's the same result in the end, people are just getting caught up in the semantics and some sort of rigid definition.
