By that unit of measure, who doesn’t have some kind of red flag? They say that it’s expected that every pitcher is going to have TJS at some point the way guys pitch. Some get hurt, recover and don’t skip a beat, others turn into an injury machine and suffer set back after set back after set back (Sale Story are good examples).
Did Albert Pujols have Red flags? He never lived up to his contract and effectively went from a perennial 1.000 ops guy to a .750 ops guy.
I think the Sox decision making is easily worthy of criticism, but you can’t predict many or not most injuries. Guys get hurt, and the older they are, the more likely they’re to get hurt or see a decline of production. This is why most free agents never live up to the height. This is why I think it’s more fruitful to criticize the Sox inability to develop and lock up young talent rather than criticize free agent signings. They’ve had plenty of guys live up to the money too
