If Jayson Tatum's injury concerns are confirmed, the Boston Celtics will not look the same again. If the greatest fears are confirmed and Jayson Tatum has indeed suffered an Achilles injury, the Boston Celtics may have no other option than to blow up the blueprint this offseason. The reality is, if Tatum is going to miss all of next season (which he would if it's a confirmed Achilles injury), it wouldn't make sense for Boston to keep this core intact this summer.
