I could be way off, but I don't think 4/$50 is going to get it done. That's less in average value than Halliday, less than Buerhle's recent 4/$56M extension. Ted Lilly got 4/$40 from the Cubs. And of course the Brewers gave Suppan 4/$42...Sheets can see firsthand what a $10M free agent pitcher looks like. While I don't want to think about Zito, and most people think SF was crazy, you know Sheets noticed that deal and thought, hey, I am a good bet to be better going forward than Zito. (Which he is, I think.) Zito's deal, 7/$126M, *averages* $18M a year. If Sheets gives up years by signing for 3 or 4 years, I'd assume he'd do so in exchange for a greater average value...say 4/$75M? 4/$80? Russ had a discussion with tangotiger about this a while back, and as I recall there was a pretty wide range of estimated value per year, but the low end in 2009 was on the order of $17M. (Edit: found it, and tango says $17M - 26M.) rluzinski.blogspot.com/20...worth.html
