Cubs have a 22 year old SS who started the major league All Star game. Torres isn't in that class. McKinney is a guy who's "slugging" .322 at AA. Seems like a guy with a high prospect rating based on who drafted him more than anything. He's shown little power other than a stint in Cal League, and no SB ability. I'm not sure they are giving up anything that will come back and haunt them down the road. Chapman gives them the kind of lock down bullpen where Maddon can pull his starter after 5 innings of a playoff game and lock the opponent down. You never know what any prospect will do until they get there, so all we can go on is where they are valued now. And right now, the Cubs are giving their #1, their #5 and another prospect, plus a warm body in Warren for a guy they are going to have for less than 1/2 a season. If the Cubs win the World Series this year nobody will ever care what Torres, McKinney, or the third guy turn into. But if they don't win it all, it was a lot to give
