That's actually a fairly legitimate concern. Obviously, no way all 4 can be superstars in MLB with the Cubs. PCA is the only one I would consider "untradable." Happ and Suzuki have no-trade clauses, but that doesn't mean they can't be traded. If those other 3 eventually start taking playing time away from EH and SS, those two would likely consent to trades if it meant more playing time. Plus, you have to give to get, and if trading away one or more of those other 3 meant the Cubs obtained a player they really need, so be it.If PCA, Caissie, Alcàntara and Canerio live up to the hype but are getting block by Happ and Suzuki I’m going to be pissed. I don’t care how much money they’re making.
