The Brewers NEED a proven closer?

So Michael Hunt from the Milwaukee Journal Sentinel went on a little rant this morning, screaming that the Brewers needed to trade for a proven closer, not Rolen or a different 3B.

While this point is obviously valid, I have a few remarks concerning the situation.

• One, the Brewers do not need a proven closer. We have not had a proven closer for a while now (even Cordero had lost his job in Texas). Kolb, DeJean, and Turnbow were all waiver pick-ups. Melvin has said many times that anyone can get 30 saves. It's the saves after 30 that are the tough ones. I think the Brewers can definitely find someone within the system (yes, even Turnbow) that can save 30 games.
  
  
• Similarly, the closers on the market are either asking too much (Gagne and Dotel) or teams are asking for way too much for proven closers (Nathan and Street). The Brewers are better off staying in the system to find the answer. While yes, we should win now, the Brewers cannot afford to mortgage the future to do so. The Crew is not a large enough market team. Stick in the organization, Doug.
