Power forward: Giannis Antetokounmpo
With the Spurs having already been linked to superstar Giannis Antetokounmpo, why not include him in their dream starting lineup? Giannis won't be able to become a free agent until the summer of 2026, but the Spurs could have cap space to sign him with Wembanyama still on his rookie contract. Adding Giannis, who will be 31 in 2026, would be the biggest signing in team history and likely made possible by Wembanyama coming into his own as a superstar.
Giannis probably will never be a good shooter, but his length, strength, and skill for a player his size should still allow him to age well, particularly when paired with another superstar to divide defensive attention. Still, he will need a team with versatile players that can maximize his strengths and minimize his weaknesses.
Having a stretch five makes his shooting less of an issue and frees up driving lanes for him to attack, which would certainly help. Additionally, having other good defenders who can take on the opposing team's best offensive players would allow him to conserve energy. San Antonio should be able to offer both, and hopefully, Giannis will have already been a Spur for a couple of seasons by the time five years come around.
