Chapman helped lead the Cubs to a World Championship.
I don't care if Torres ends up some day in Cooperstown. It was still a great deal for the Cubs.
It's not like the Cubs were mortgaging the future for the present. Their infield is loaded with young stars and is set for years to come. They are also under club control for the next several years.
Having a loaded farm system and an All Star infield means you can trade the prospects to fill holes. Theo did just that. It was a no-brainer.
