It's more than that - at least in Torkelson's case. My compliant is the Tiger approach as per the way Tork has described it more than once, gives the pitcher no credit for being able to command the strike zone. "Take a strike until you get a pitch you can drive up to strike two" then go to survival mode, is I think, a recipe for failure against any but the worst pitchers. I think the 1st strike - fine - but after strike one you have to shift to contact mode because strike two is too late. The Tigers take too many pitches that can be hit. Maybe not for HRs but that they could put in play in better shape than an emergency swing on strike two. I would even go further to say that every pregame approach to looking for a zone has to go right out the window once you see what a guy is actually throwing and what an ump is calling. If you park yourself waiting for middle in and he is painting the outside, plus the ump is calling a ball's width on top of that to the outside, and you take a thigh high fastball on the outer third not understanding that you are just going to get something further away on the next pitch, all I can say is good luck to you.
I would like to the focus to move more toward covering the strike zone rather than looking for zones. Any one can do the latter, but a good development program and batting practice habits should be able to improve the former. And I still reject that more than one or two players on a roster are ever swinging at balls they know will not be strikes. That is the other place I think the mantra breaks down.
Now eventually, they will sign only players that fit that mold, that already have good pitch recognition, and for them the coaching in that direction will be superfluous but the staff will look like geniuses!
Anyway , it is what it is, the spitballing is mostly for entainment (at least in my case)...so YMMV.
