Golden State Warriors head coach Steve Kerr is not pleased with how his team is rebounding thus far.

It's only preseason, but Kerr points out the Warriors are the second-worst rebounding team in the preseason, which includes some international teams since the NBA has taken on some teams outside of the U.S. in the preseason.

The Warriors are missing centers Willie Cauley-Stein and Kevin Looney at the moment. As a result, the Dubs are really small and having a hard time finishing possessions by grabbing the defensive rebound.

Guys like Marquese Chriss and Omari Spellman have to help out Draymond Green on the boards until Cauley-Stein and Looney are cleared to play. Because Kevin Durant and Andre Iguodala are gone and Klay Thompson is expected to miss a big chunk of the season, the Warriors don't figure to be a great defensive team in 2019-20, which means getting rebounds is going to be crucial for the Dubs.

The Warriors finish off the preseason with three more games against the Los Angeles Lakers. They open the regular season on Oct. 24 at home against the Los Angeles Clippers.

In these final exhibition games, Kerr and his staff are going to be focusing on the rebounding battle and hoping the Golden State players are using the proper technique to box out and grab the rebound.
