I predicted that Shohei would sign with the Dodgers in Free Agency towards the middle of the season. It made too much sense. For those of you bashing him for leaving and going to the Dodgers, can't fault a person who gave it his all to a poorly run organization, then decided to go to a team with great management and track record of winning, while also giving you top dollar. No one here would do reject that offer, so why do you expect Shohei to? All of us would leave a job with crap management & support staff to a rival company that has better management & staff, and offers you much more money.
As for the move itself, Shohei is perhaps the best pure hitter and is worth, as just a hitter around 4-6 WAR. This alone would've gotten him a contract in the 10yr/350-400 million range. His career hitting stats is pretty much inline with David Ortiz's stats in terms of OPS and OPS+. His pitching stats also give him another 4-6 WAR a season for the past 3 seasons, which would've given him a contract of the same range as a hitter had he not have had a 2nd TJ surgery. While the price tag is insane, it's not out of this world that he got it. Hard to say how he'll do pitching wise after the surgery, but I wouldn't doubt him. I do worry about the wear and tear and injury concerns as he approaches the mid 30s. A tremendous risk, but one worth taking for a tremendous and unique player.
Sad to lose the unicorn, and I'll miss watching him every game.
