Therefore Joe Mauer should swing less than Adam Dunn.
Mauer isn't a power hitter, and never has been. When you accept this then Mauer's approach makes perfect sense. It maximizes output from a skillset that's frankly more limited than people think. Certainly more limited than Dunn's.
Consider, in 2012, Mauer needed 98 swings to hit a home run. He needed 3.0 to produce an out.
Dunn needed 29 swings to hit a home run, and 2.8 to produce an out.
Two different batters, two very different swing-take equations. If anything, its remarkable the results were so similar. It just shows how incredibly good at collecting hits Mauer was, and how incredibly bad at collecting everything that wasn't a K, BB, or HR Dunn was.
They're a fun tandem to compare.
