In a rebuild, like the Cubs did it.....teams sign older players to 1 year deals TO DEAL THEM LATER, it is one way to buy prospects, basically. The Twins, otoh, signed guys to 1 year deals, then re-upped them......and did not trade them. So, if you think the team is rebuilding, you might do this. Also, since they have had zero good CF since they decided to trade Span for nothing, it seems reasonable that you might sign a guy that can play CF and SS and 3B (maybe), in case your Buxton and Escobar plans went south....... not saying I'd do it, but I can understand why you would.
