I think the Cubs ought to be a combination of buyers and sellers. Trade Bellinger, Taillon, Hendricks, Smyly, Hoerner, Happ, or Suzuki for prospects, while trading PCA, Morel, Alcantra, Triantos, etc. for young controllable stars like Guerrero, Robert, Luzardo, Woo, etc. It's great to have all of these top prospects, but players like Mervis, PCA, Amaya, Morel, etc. have shown that minor league stats don't always translate into major league success.
