The Sacramento Kings are invested into adding a new center this offseason, and they could do so even if they re-signed free agent forward Harrison Barnes, according to ESPN's Ramona Shelburne and Brian Windhorst.

The Kings have looked at the likes of Nikola Vucevic and Brook Lopez, but to sign them would require them to renounce Willie Cauley-Stein, whose agent has asked the Kings to let him go.

Sacramento has the cap room to make center Al Horford an aggressive offer, but the former Boston Celtics big man has a list of teams already willing to shell out the money for his services.

Vucevic is in murky waters on his potential to re-sign with the Orlando Magic, while Lopez played one year for head coach Luke Walton with the Los Angeles Lakers in 2017-18.

The Kings had hoped Cauley-Stein would give them no choice but to re-sign him this summer, but the fourth-year Kentucky product has failed to live up to GM Vlade Divac's expectations, regressing with his free-throw shooting and failing to become the shot-blocking presence that Divac had envisioned when first drafting the 7-footer.

Both Vucevic and Lopez boast a perimeter game to go with their size (both legitimate 7-footers).

Vooch is coming off the best season of his career, averaging career-highs across the board with 20.8 points, 12 rebounds, 3.8 assists, 1.0 steals, and 1.1 blocks per game.

Lopez has revamped himself under coach Mike Budenholzer, becoming a stretch-five 3-point shooting specialist that shot 36.5% in the regular season and 29.3% in the postseason.

Either player would give the Kings a refreshing new look at the center position while still bringing in Marvin Bagley III as an up-and-coming double-double presence.
