2.) Cedi Osman
Spurs wing Cedi Osman has likely been the biggest surprise for the team thus far. He was included as salary filler in a 3-team trade with the Cleveland Cavaliers and Miami Heat and it looked like he might be waived by the Spurs before the start of the season. That didn't happen and it's good that they didn't, because he has been arguably the team's best bench player, averaging 8.5 points while shooting 43.7% from three.
He's also been surprisingly aggressive, attacking on offense and competing on defense, helping to provide a boost off the bench. Osman is currently logging around 20 minutes per game, though he could stand to see a few more minutes each game with the Spurs potentially going small more often to make it happen.
Thus far, that is something that Popovich has seemed unwilling to do with Wembanyama being paired with Zach Collins or Charles Bassey for the vast majority of his minutes. Though if Pop decides to experiment with smaller lineups, Osman would be a likely beneficiary given his terrific play to start the season. Moreover, the Spurs would be better for it.
