Yeah, likely. Because JF seems to me a traditionalist. And this theory of the k-ball's ineffectiveness (and it is only a theory) involves science, that is to say, basic meteorology. I'm pretty sure JF, like all baseball commentators I have ever heard, would talk vaguely about the "heavier" air during wet days, which in turn prevents the ball from traveling and would slow down the kball. (This of course is completely untrue--air in high pressure areas is heavier. But --has anyone ever checked it?--it may be true that hitters, for other reasons, don't hit the ball as far in damp weather.)
