The argument comes down to the value of the closer role. About this, there is no consensus. If you think a closer should be paid like a set-up guy and traded as soon as he acquires enough saves to give him sufficient trade value, this is a bad deal. If you think a closer is difficult to develop and should be held onto as long as there is a chance at a championship, this is a great deal. I have seen enough of closers like RD, LaTroy and Crapps to fall in the second camp. Besides, I don't think you create one hole to fill another. By all means, find a way to build a winning rotation, but don't do it at the expense of the bullpen. I also think your claim that in three years the Twins will still be one pitcher short of a top 5 rotation a bit dubious. They certainly have the arms to put together a top 5 rotation. Whether that happens is too speculative to base an argument on. If your claim is suppositional (i.e. supposing they are one starter short of a top 5 rotation in three years, then they could use Perkins to acquire that guy), then it makes some sense. But I still disagree with it. First of all, I have yet to see a trade of a closer for an ace straight up. It would take multiple pieces in addition to the closer to acquire an ace. As long as you're including other pieces, that's not the time to trade major league assets for major league assets. That's the time to trade prospects for the likes of David Price.
