I don't get why people keep talking about Prince, then looking at Mo Vaughn and thinking that's a terrible thing. During his age 30 season, Vaughn hit 40 homers with 117 RBIs and a .402 OPB. During his age 31 season, he hit 33 with 108 RBIs and a .358 OPB. During his age 32 season, he hit 36 homers with 117 RBIs and a .365 OPB. Then he got hurt. When he came back, during his age 34 season, he hit 26 homers with 72 RBIs and a .349 OBP. That last season is not great, of course, but that would be Fielder's seventh season of a seven-year contract. So, if Fielder produced like Vaughn did from his age 28 season to his age 34 season, why would that be bad again? Somewhere around ~2.0 WAR is average for a position player in a full season. He went from 6.6 WAR (slightly better than Fielder's peak) in his last year in Boston to totals of 1.9 and 2.0 the next two seasons, missed a year entirely, then came back out with a 0.8 season and a sub-replacement level -0.6 WAR before leaving baseball entirely. He was never an above average regular after signing his big contract. I've said it before and I'll say it again... players with the body type and skill set that Prince Fielder has peak very early and do not age well. There is no gradual decline. It's a nosedive off a cliff. Now I'm not saying I don't like Prince Fielder at all. But he's the kind of piece you add to put yourself over the top in the next few years... not the type to build around for the long term. Give him 5 years and I'm happy. Give him 6 years and show me a blueprint that has us competing sooner rather than later and I can probably live with it. If we have to pony up that 7th year, I'd rather we be shopping in the bargain bin.
