Question 3: How do the new additions affect the Spurs' young core?
With a total of 13 players aged 26 and under, San Antonio will have one of its youngest rosters in team history. With so much youth, finding minutes for all of them to develop can be difficult, especially with players like Collins, McDermott, Forbes, and Young now in the mix.
The addition of Collins, Young, and Landale could affect Drew Eubanks, who emerged as a solid rotation player last season. Collins, while definitely talented, has struggled with injuries, and is coming off a second surgery on the same foot. That said, if healthy, he could provide the Spurs with an upgrade over Eubanks at backup center.
Landale, a 6-11, 3-point shooting big from Australia who can block shots and rebound, is another option at center. However, I wouldn't expect him to play much next season. However, Thaddeus Young could. Young is known as a good defender, an underrated passer, and is a career 33.1% 3-point shooter. Additionally, he mostly played center last season though has mostly played power forward for much of his career, meaning that he could play both positions next season.
As for Luka Samanic, who is entering his third season, he may struggle to find minutes. With McDermott possibly starting at power forward and Young possibly playing some backup four, Luka could have limited opportunities to prove himself.
Now that Mills has signed with the Brooklyn Nets, San Antonio could turn to either Forbes or Tre Jones to replace him off the bench. Jones has flashed strong playmaking and defensive ability in limited minutes and in the G League, although I question his ability to score consistently in the NBA. Forbes, despite being a shooting guard, could theoretically fill that role.
As for Lonnie Walker IV and Devin Vassell, I could see them both benefitting from the departures of Rudy Gay (who signed with Utah) and Mills. Considering that both veterans had a score-first mentality and often took shots away from younger players, with more opportunities to create, Walker and Vassell could make solid strides next season. In regards to the Murray, White, and Johnson trio, each could take on more play-making and scoring responsibilities next season.
It remains to be seen whether all of the Spurs offseason moves will ultimately work out. If they don't, then the offseason could be considered a disappointment. However, if they do, then the offseason could be viewed as a success and crucial towards helping San Antonio make it back to the playoffs.
