Honestly, I don't think he should be playing regularly. Not many teams can afford Brantley's level of production - offensive or defensive, and certainly not both - out of a LF. Brantley is part of the reason that Cleveland has a below average offense. Developing power is just a natural thing - as you get older, you get stronger. Developing a better eye at the plate comes with repetition - the more pitches you see, the better you should (theoretically) be able to recognize them. I don't think latent is the right word, but certainly different guys have different potential at different things. IMO, Gindl has the potential to perhaps be a 25-30 HR guy in his prime if everything (and I mean everything - that's probably unrealistic) works out right. Right now he has an ISO of about 170, which is more or less commiserate with the rest of his career. If he posts an ISO of 230 in MLB in his age 27 season, will he have developed a new skill then? I guess it boils down to semantics. I say no - the potential, or a portion of it, is merely being fulfilled. He also may never surpass a 110 ISO. Who knows? Brantley's ISO rising from 80 to 110 isn't a new skill, it's just his power closing in on its absolute potential. He's getting older, stronger, and he seems to be more willing to swing at pitches out of the zone to try to up his power. He's also missing on a lot of those pitches. The ideal place for him to be is where both his power game, such that it is, and his plate discipline can coexist. Maybe we're talking past each other a little. I get your point, that it's easy to get caught up in "now" production. But, I think most people realize that Gindl will probably get stronger and develop into something different than he is now. Or maybe they don't.
