It took 68 games, but the Spurs finally suffered their first “major” injury of the season in Saturday’s loss to the Pacers when starting power forward Doug McDermott landed on Oshae Brissett’s foot and suffered a grade 3 ankle sprain. (That’s the worst type of sprain and can sometimes take longer than a broken bone to fully heal.) It was then announced on Wednesday that he would miss the remainder of the season as the team is fighting for its playin life. While it would be an overstatement to say this is a massive loss for the Spurs, it’s the implications McDermott’s absence has on the rest of roster — and what it reveals — that can’t be understated.
