Make this a blog. Really, we'd love to see it. It's one of the most interesting points for the Twins moving into 2013. Personally, as (I believe it was Thyrlos) pointed out, the Twins have been paying Morneau $14m to be a 1 WAR player. I think he'll finish this season well above that (maybe a 1.5 WAR) player but that's still a hell of a lot of money when you have a first baseman in AAA posting an OPS of 1.115. I see it like this: You let Justin play. If he's truly back, you have a HUGE trade chip starting in May. You fit Chris into the lineup everywhere and anywhere you can and let him play as much in Minnesota as possible. If, in June of 2013, you are in a position of strength to trade, you do it. Let Chris fail or succeed on the ML level and then you treat Justin appropriately. Of course, much of this depends on trading Span to clear room in the OF so Chris can get ML ABs.
