Pedro is the one pitcher who can have his cuff repaired and will still come back and be special. He isnt a guy who absolutely needs his velocity. He has some 3-4 plus offspeed pitches that he can locate on a dime. He lost one yr, but will likely finish this season as the mets ace. Either way, at the time, the sox had no idea he'd be a one and done. They thought he'd be a 3 and done. They offered him 3, and if he took that, he'd be missing this season too. It isnt like they saw that he was beat up and passed now, they made an attempt.
As far as theo being on thin ice, I see it something like that. The sox were huge spenders this offseason on guys who are anything but sure bets. Matsuzaka never pitched in the bigs before. Drfew has trouble staying healthy. Lugo has been a solid player for 1.5 seasons in his career and has had trouble keeping his fists off his wives. He built a pitching staff that looked solid on paper and then forgot about the closer, then took their brightest young arm and threw him back to the closers role against the advice of the doctors. They seem to be relying on Lester as the 5 in a few months, knowing he still wont be all the way back. LOTS of things theo has put his neck out there for and I think most of them will work out. But there is also the slim possibility that most of these go down in flames and leave the sox holding the bag for a major shitfest. This offseason was the rubber stamp of their immediate future. If it bombs out, theo is toast.
