Umm, yes really. There's more to location than balls and strikes. WHERE you miss is important
While true, Bard doesn't make a lot of mistakes in the zone, and that's reflected in his numbers too. If he misses, it's a ball. WHEN Hansen misses, it gets clobbered.
Also, consider the standard we're applying here. I'm not exactly claiming that Bard is Takashi Saito, just that he doesn't suck as bad as Hansen.
