I am probably a little hyperbolic, but if we are not doing well in mid-May, then there seems to be many who say, "Blow it up! Get as many prospects as you can."
I would want to trade Peralta for the right reason. If he was at the end of his contract and the Brewers would have to pay a huge amount of cash, then I think it would be a good idea to move him. If we are moving him simply because we need to get prospects and rebuild, then I do not agree with that.
I am not saying prospects have no value. What I am saying is that just because we get prospects doesn't mean they are necessarily going to equate to something at the MLB level. There is a bit of a gamble. In regards to the Adam Lind for Peralta -- that worked out well. Some do, some don't. I have seen plenty of articles on how trading for a particular prospect yielded good things two, three, or four generations (trade-speaking) down the road. When Lucroy was traded, they had Martin Maldonado and Manny Pina behind him (Maldonado couldn't hit his way out of a wet paper bag that year). Also, the trade was done at the beginning of August, so the Brewers had thrown in the towel -- finishing fourth.
My (probably incorrect assumption) is that people want to get many prospects because in 2, 3, or 4 years they will be contributing to the big club. I can't agree that is always the case.
Perhaps my apprehension towards blowing it up is that the margin is so small for the Brewers. I have lived through the Brewers crappy period after '82, the Badger football team being terrible in the 70's, the Packers being abysmal, and the Bucks not making the playoffs after Ray Allen and Big Dog left.
So, I'm on board toward trading veterans for the right reason. Simply trading veterans to get prospects -- not so much. If they can pull it off and stay in the playoff hunt (almost) every year, then I'll be on board.
