When he's not still thinking about how badly he wants to beat up Derek Fisher, Matt Barnes can be found giving some heated and passionate opinions on basketball. Of course, Barnes is a former player and enjoyed a stint with the Phoenix Suns during the 2008-2009 season. Barnes still pays attention to what does down in Phoenix and on Twitter this morning, the former NBA player lashed out at owner Robert Sarver for the way he's been running the team.

The Suns have some exceptional young talent including Devin Booker who put up multiple 50-point performances this season. Barnes feels as though Sarver is currently wasting Booker's talents and that Sarver should actually consider removing himself from the team entirely.

"Coaching isn’t the problem w the Suns] the owner is!" Barnes wrote. "Sarver is the worst owner in the NBA.. Do that great city phnx a solid & sell the team, they deserve a winner! You’re wasting Devin Bookers career."

The Suns recently fired their head coach Igor Kokoskov after just his first season with the team. The Suns finished the season with a record 19-63 which put them last place in the Western Conference and tied for 29th in the entire league.
