Hunter was better than Young in 2012, I don't think that's anywhere near a certainty in 2013. Hunter is old and had an extremely lucky season. You're also looking at this the wrong way, the opportunity cost of this move is what will really hurt the Tigers. What else could they have gotten for $13,000,000 over the next two years? Can you get, for example, Nick Swisher (a significantly better bet to help your team) for that?
