True, I maintain a low regard for the baseball acumen of the average fan. Anybody that seeks out a forum like this, and posts to it regularly, is already far more credible than the average fan in my mind.
To your point about trade value, I have no disagreement. However, I don't think it is a feasible scenario depending on your definition of "immediate longer term offensive help". My version of that is a 1-2 year guy who could be penciled in day one after the trade at 3B, and be legit expected to hit 12-15 HRs the rest of the season and around .265 or better... AND be affordable for the Brewers small market constraints. I'd take that in a heartbeat too, but nobody is going to offer that kind of hitter for Perralta, Quintana, or Civale. In the perfect situation, you might get that in return for Hoskins, but then MKE is guaranteed a hole at 1B for the next couple of years. I'm not a casual fan, but even I am not interested at this point in A - A+ prospects from trades. The Brewers already have a crowded farm system overpopulated with exciting prospects. They need proven MLB quality hitters right now, and they're not likely to acquire them in selling. Durbin was that A - A+ prospect, and he's a high quality utility player, but he's not the thumper they need more of. Moving Perralta for another "Durbin" (who I do like BTW) would be a poorly timed, negative PR optic in my view.
