First, let's make some assumptions. I feel like 5 WAR is a pretty safe bet for the Prince. That's worth about 20 million right there and lets say he comes in at 15 million in arby, so you've got about 5 million in surplus value. Casey is a little trickier. I think his true talent level is about 3 WAR. So over 4 years you get 12 WAR which is worth about 48 million. How much is Casey going to make over this time, though? Using the 40/60/80 arby model I get a total of about 32 million (.5/4.5/7/10) which puts his surplus at 16 million. It would seem like Casey has more surplus value, but that's not the whole picture. Prince's floor is probably higher than Casey's ceiling at this point. Prince has a longer track record of greater success while being two years younger. He is a HUGE (literally) LH slugger. He is only a one year commitment. Casey is cheap the next couple years. He plays a more premium defensive position. But he also has more uncertainty about his production moving forward, it's easier to be confident about a 1 year vs a 4 year projection. It obviously depends on what the trading team's needs are but I still think Fielder will net better offers than McGehee this offseason. Hows about you?
