A bit of a 180 by Isaiah Thomas on the Celtics right here. If you recall Thomas has previously stated that he believes that both Brad Stevens and Danny Ainge were more concerned about Isaiah's future than just getting him back on the court that final season in Boston. Thomas also has stated that the Celtics had multiple people come to talk to him about the risks of playing through his injury.
Regardless I think the Celtics could have done more. Maybe forced Isaiah to not play, but again he's his own man. Boston ended up firing their medical staff that offseason for what it's worth.
