You have no way to claim that if he is overpaid, it will be significant. Why not? Are you sure you know what Lee's remaning contract is? He is owed $18.5M per year through 2012. Right now, if we just take Fangraphs value as the baseline, the Astros are ahead $4M for the first two years. Lee's highest value was last year at $15.3M and his second highest is 2004 at $14.9M. If I average the last three years, his average value has been $12.47M/year. If I just say that Lee will be worth $12.5M per year over the next 4 years, the Astros will have overpaid by $6M/year for 4 years. For the life of the contract, they will have overpaid by $20M. There's a lot of assumptions in there. There is the assumption that value wins are maintained at the same salary level over the next 4 years. Its my belief that they will decrease in 2009, and probably in 2010, and I don't have a reasonable guess for the last two years. There is the assumption that he will maintain a high level of performance and durability through his age 36 season. I think it's likely that the Astros will have overpaid by $20M, and I think it's highly possible that they will end up overpaying closer to $30-$35M by the end of the deal.
