No disagreement there. However, the solution (look to hit the ball up the middle or opposite field) also addresses everything but the FB up in the zone.
When you're committed to going oppo, you see the ball longer because you let it travel (more time to lay off), your hips stay closed longer which extends your ability to cover the outer half (especially low/away), etc. There's really only one swing-and-miss pitch and that's a heater in or up/in.
In contrast, when you're playing hero ball and trying to pull everything, everything BUT the FB can be a swing-and-miss pitch (you're out in front), your hips open early, you can't barrel up the outer half, and you're just early in general (which means you have to decide sooner...less time to see it).
When I was a kid, I remember my dad wouldn't wrap up BP until I hit 50 straight balls to the right side of 2B. If I was in a slump, he'd up it. It absolutely works.
