San Antonio Spurs wing Julian Champagnie has agreed to a new contract that will spread $45 million over the next three seasons, a league source confirmed to The Athletic.The Spurs wing broke the franchise’s record for 3s made in the regular season with 195, surpassing Danny Green’s mark of 191. When coach Mitch Johnson moved him into the starting lineup in February, replacing veteran Harrison Barnes, the Spurs went on a tear and were the best team in the NBA in the second half of the season. Champagnie averaged 11.1 points and 5.8 rebounds on 38.1 percent 3-point shooting this past season, as the Spurs made it all the way to the NBA Finals.San Antonio’s salary-cap situation is manageable today, even as De’Aaron Fox’s max extension kicks in this season. But with Victor Wembanyama, Stephon Castle and Dylan Harper all likely to get max extensions over the next three seasons, the Spurs needed to lock in Champagnie to a mid-sized deal now. He would have played on a $3 million team option and become a free agent after next season. Now, the Spurs will have him locked up on his new deal.With Keldon Johnson entering the final year of his deal at $18 million, Barnes hitting free agency and Vassell having three years remaining at roughly $80 million, the Spurs have a well-priced shooter who fits their long-term plans while still providing flexibility. Carter Bryant showed flashes of becoming that guy with more development and could be the solution eventually. But this team needs as much shooting as it can get.
