The addition of Luke Kornet was the San Antonio Spurs' big off-season move and has been treated as such by fans. While Kornet is a big get for the Spurs, his role may not be quite what fans are expecting.
If Victor Wembanyama is as healthy as he was during his rookie season, Kornet likely won't play more than 18 minutes a game next year. His signing was to solidify the backup center spot, which was a huge weakness for San Antonio, and adding him was also meant to bolster the second unit's defense.
He should do both of those things and more than justify his $10 million salary for each of the next 4 years.
