How much good does that bit of information actually do a hitter? He has to recognize the pitch. If he does, his expectation about it is immaterial, because he sees it for what it is. If he doesn't recognize it, he's still swinging or not based on a guess. OK, I'll stipulate that early in the game, if you are ahead in the count and decide to sit on a pitch, then you should sit based on tendency. But once a game has played out for while, what is and isn't working for that pitcher in that particular outing will in most cases become more important data for the hitter than the pitcher's overall tendencies. But I don't even think that is what the Tiger hitters suffer from. They are taking too many hittable pitches and getting behind early too often and then uncertain about what they are swinging at too often when they do swing (the dreaded "in between" swing). That really has nothing to do with advance scouting reports, it has to do with basic approach, confidence levels, and how coaching and management expectations and feedback relate to that is probably a lot more subtle than anything to do with the hard data or preparation of advance scouting.
Now, if none of them do anything other than what they are doing now, or in a career after leaving the Tigers, then we will know they were all simply poor hitters. But if in a few weeks or two months this team is starting to hit league average scoring levels like they did after June last season, then I will argue the coaching staff is responsible for some kind of poor psychological season prep!
