An absolute steal. Low risk and high reward. He does bad oh well; one year deal and he is gone.
He does good and the Padres are doing well then he helps them. If he does good and the Padres are still retooling then they could deal him for prospects OR QO in the off-season and get a 1st round pick as he is likely to decline and look for his "Greinke-esque" deal.
The reason the money isn't higher isn't because of injury risk, it's because he sucked *** last year.
Well, the injuries that he had last year almost certainly did factor into this contract. That's obvious from the structure of the contract - incentives for games started and the option if he can't start a minimum number of games
Padres could be the sleeper team in the NL this next yr. I Jobnson stays healthy they quietly have a top 5 rotation and a boatload of younf arms to deal for an impact bat to go with a really quality lineup when healthy. Keep an eye on them
