"Recall the Jayson Werth deal. Werth hit free agency after his age-31 season, with a small handful of very good seasons under his belt. Like Cain, injuries and foolishness on the part of the team trying to develop him delayed Werth’s establishment as an everyday player, but he was a guy with a broad base of skills and tremendous overall athleticism. He signed a seven-year, $126 million deal with the Nationals, to the shock and chagrin of many observers. Over the life of that deal, however, Werth was worth 16.9 WARP, meaning that the Nationals paid about $7.4 million per win—hardly a bust, especially considering that much of that value was concentrated in the first four seasons of the term. Cain is unlikely to even approximate Werth’s payday. It would be no surprise, now, if he were forced to settle for, say, a four-year deal worth $80 million. At that price, he would be an outlandish bargain, and if he comes in even lower, he’s going to give some organization a huge boost." https://www.baseballprospectus.com/news/article/37070/rubbing-mud-lorenzo-cain-still-available/
