The answer to the OP's question is a resounding "NO!", and there really can't be any legitimate debate on it. Selling now would be suicide for this franchise in terms of business and in terms of fan perception. We have an excellent chance to see the Brewers win an NL Central Title, which would be a franchise first. Yes, I'd love to be able to say, "This team will go the World Series!" today on July 18th, but that is just asking too much. That doesn't mean you sell off now, though.
