There are myriad ways and reasons he can be traded for "a player who is already better than he is". But to be crystal clear, in my opinion the Cubs are in no position to trade him for minor leaguers. If they trade him the need to get better by the trade. It is not a good sign for 2014 if they trade him and don't get better. I don't see why it matters since they aren't likely to be competing for the division with or without him this hear. He's been very inconsistent with occasional bouts of greatness. He's shown enough that we could probably entice someone to give up a good package of prospects for him this offseason. My opinion is that he's a mid rotation starter but can bring back more value than that in a trade, so they should pull the trigger in that scenario. I realize there are people who think he's a future ace, but I don't see it.
