This is the key for me. Too often, teams hold on to the guy while he's cheap and they try to sell off the overloaded back end, eventually getting pennies on the dollar -- or nothing.
When a team is in talent accumulation mode, as we should be, those cheap years represent trade value. You can't wait until after 2010 and then try and flip him because he's too expensive. And we're not going to be a WS contender in 2009. So rather than realize that value on the field in '09, we're best off realizing it by turning it in to an asset that will be useful for years to come.
