I don't think I'm philosophically that far off from you, as you may think. I honestly just don't see how you don't see the Brewers doing exactly what you are advocating.
I agree that what we're saying is probably more aligned than not. I think there are several points of agreement, including:
1) The Brewers did the right thing leading up to that NLCS run
2) They've done a consistently lousy job of drafting/developing since that core reached the majors, especially at pitcher and internationally
3) They did a nice job flipping Greinke for solid assets
Post-NLCS run, here are the things I don't like (some of which you may agree with and some of which can just be an honest point of disagreement among fans):
1) Trying to plug pitching rotation holes with FAs. In 2008, I'd love an aggressive move for Garza or Lohse. But now...I don't fully get it. Even though we suck at drafting, I'd prefer we fix that with the front office than forfeit a pick for a guy like Lohse. Lohse is a fine pitcher, but in the large scheme of things, it's highly unlikely he or Garza are enough to even get this team in the playoffs, let alone do anything when they get there. I'd rather see what are young arms can do then invest $ or give up picks for FAs.
2) Obsession with veterans who don't contribute that much. Obviously Yuni. This year, why bother with Overbay or Reynolds or Francisco at 1B? Just give the job to Morris and see what he can do.
3) Not dealing veteran assets. The Greinke deal was great. Not clear why we never dealt Hart or Weeks or Ramirez when we had the chance. I'd add Gomez to that list now as well. Again, those are all players I'd hold on to if I was close to contending, but if we're not drafting well, we need to get talent somehow, and these are the guys I would look to deal.
So while I loved the investment and philosophy Mark A and Melvin had leading up to the NLCS (and the fans deserved that by the way), I feel the success of that run has paralyzed their thinking. Likely they don't want to take a hit at the box office. Or perhaps they realized it workd in the past for going for it, so they think they can do it again even though the circumstances are different. Whatever the reason, I think their current approach may lead to another dry spell for Milwaukee. Teams like Oakland and Tampa have shown how a smaller market team can compete -- and it's not by trying to make noise in FA. Pitt has caught on as well. On the flip side, you've got big market teams like St. Louis and the Cubs in your division that have just gotten much smarter about how they spend their massive resources. So the Brewers need to be smarter to compete in the future and I think they are investing in the wrong area (Lohse, Garza) rather than in gutting and building out a first class scouting department
