How many non pitchers have some degree of damage in their elbow and rest and rehab works?
I know it depends on the extent of damage, which may or may not be known precisely and what position the guy plays, like SS v 1B, but my guess is there are dozens and dozens of MLB players who have gotten bye without surgery. Correct me, if I am wrong.
Again, I'm not saying mistakes weren't made or that the blame should not be focused on just one or maybe two guys, but it's not a clear issue, at least right now. We may or may not find out details, later that focus more of the blame on one guy over another (or more,) but right know, we can only assume.
I do think it's safe to assume Story, Bloom, JH, top brass and the team medical staff knew there was an issue and a risk. They made the wrong choice based on accurate or faulty information. We don't know, if there were factions within those who made the call that swayed the decision to sign Story, or who was in opposing factions, if there were some. They may have all known the risk, but thought he was worth it. Hell, for all we know, they may have decided that even if he missed a year, he was worth about $140M/5, too.
It's not a simple process or decision.
On the Sale signing, I do think they expected he might miss a full season and would still have been worth $145M/4, too. That's just my opinion, and it looks like Sale's deal might end being more like $145M/ 1.5 or $145M/2.
