I'd say claiming he's the best hitter points to that not being true for some but that's beside the point. This is an extension of the same strategy as trading Hader. We just have to accept our best players, obviously given Renfroe was our best hitter he qualifies as that, are going to be traded before we have to let them go for next to nothing. I agree with that strategy. Even if I didn't, I can at least recognize that is the strategy and not get bent out of shape every time it happens.
As far as what we got in return I said I don't know enough about them to say much about it. Then again neither do you. Nobody does outside of reading up on what they've done so far. Yes they are from a system devoid of pitching prospects but is that because of poor development or poor pitchers? Lets get them here and see what we have before determining they have to suck because they come from a team that can't produce good pitchers. One year of Renfroe wasn't going to get us a can't miss prospect but that doesn't mean it can't get us more value than that one year of Renfroe.
