But a player could generate a good swing, a desirable swing, ... the kind of good, desirable swing that would've sent the ball traveling over the Shea outfield fence for a HR ... and that same swing and contact will result in an out at Citi Field, a significant number of times. ...or a double or triple off the wall; and HRs on the road. I don't think you tailor your swing to your park. You only play 1/2 your games there, and a good swing is a good swing, and will result in good contact more often than not, which will often result in production. Screwing with the swing, however, because your TRYING to hit HR in a big park, or trying to avoid putting it in the air, or whatever, is far more problematic. I don't think the coach is saying anything particularly controversial here.
