For four consecutive years, the Detroit Tigers sat comfortably atop the throne of the American League Central Division. Last year, they relinquished that reign and did so in dramatic fashion, fielding the franchise’s worst rotation since the 119-loss Tigers of 2003 while plummeting to last place in the division.
Clearly, the Tigers were going to add a pitcher or three in the offseason. The question was, would it be a series of band-aids to stop the bleeding, or something bigger to put them back on the attack? On Sunday, that question was answered, when the Tigers agreed to terms with Jordan Zimmermann.
Those terms, precisely, are five years and $110 million, which is less than the 6/120 that our crowdsourcing project predicted. In past years, the crowd has tended to err on the low side, especially with high-profile free agents, so any time a guy signs for less, it looks good for the team.
In fact, if you start with Zimmermann’s +3 WAR Steamer projection for 2016, assume he ages somewhat well and factor in inflation, Zimmermann’s contract comes out as a carbon-copy of what would be considered the fair, market price:

What the Tigers are paying for here is consistency. This is a team that gave 147 innings to Buck Farmer, Kyle Lobstein, Kyle Ryan, and Randy Wolf last year, and a team whose only qualified pitcher was Alfredo Simon. Even at the top of the rotation, there’s former workhorse Justin Verlander, who looked like his old self once returning from injury but still needs to prove he can throw 200 innings again; Anibal Sanchez, who has either been hurt or ineffective each of the last two years; and Daniel Norris, who’s never thrown more than 150 innings in professional ball and just had a cancerous growth removed from his thyroid.
