The first part is opinion. You and I are not equipped to know if any of them could have been prevented, period. So please don't imply that your opinion is more valid or fact based than mine. Secondly, I'd sure as hell hope the doctors are giving imput into more than just the diagnosis and surgery. I'd hope they have some input on training, mechanics, rehab vs. surgery odds, recovery, etc. If they don't, perhaps that is a problem. Yes, I'm speculating. But so is anyone saying that better medical staff could not have prevented any of them. Both are speculation, period. They are part of a competitive, zero sum game. It's not possible that all teams have exactly equally talented medical staffs. It's perfectly fair to wonder if there could be improvement there. No different than wondering if they could improve the pitching coach, or regional scout, etc.
