The problem with making this part of your strategy, is you have to outbid 29 other teams to do it. And then when it's time to flip him, you can have 29 teams replying "I didn't even want him at that price, free and clear. Now I need to give you a prospect for the right to pay him that same salary?" Yes, of course such trades do get made, for a variety of reasons such as key injuries, but the obstacle is still there if you're truly basing your strategy around the idea. How much could the Twins get for Correia or Willingham? For that matter, how much could their respective teams get for Greinke or Anibal Sanchez? The Feldman trade looks to me to be about the best you can hope for, and the downside to the strategy is if you acquired Willingham only to be a trade chip after a year, and have him end 2012 disabled instead and a shell of himself in 2013. On average, I think, the strategy won't fill up the farm system with very many prospects.
