To stay fresh during the grind of an NBA season, Warriors guard Klay Thompson eyes a series of personal goals. Thompson revealed Monday after shoot-around that membership in the ultra-exclusive 50-40-90 club isn’t his only individual objective this season.

“I’m trying to average one block a game,” Thompson said. “For a shooting guard, that’d be really good.”

Arguably one of the greatest shooters in NBA history, Thompson’s offensive prowess often overshadows the fact that he is an elite defender. His blend of stamina, size and unyielding will has made him a daunting on-ball matchup for everyone from LeBron James to Russell Westbrook. Now, 10 games into the season, Thompson is on pace to have a career-high 0.9 blocks per game.

Twice this season, he has swatted multiple shots. Midway through the fourth quarter of Thursday’s 112-92 win over San Antonio, after blocking a LaMarcus Aldridge dunk attempt, Thompson was so pleased with himself that he turned the ball over seconds later.

“Felt great,” Thompson said of the block. “Until I turned it over. Then got pulled out. That’s karma for you.”

Averaging a block per game would put Thompson in unusual territory. Of the 38 players currently at that mark, only two — Washington’s John Wall (1.1) and San Antonio’s Danny Green (1.1) — are guards. Only one guard — Oklahoma City’s Andre Roberson — was among the 35 players to average a block per game last season.

“I don’t know how many (guards) are doing that, so that’d be really nice,” said Thompson, who has never averaged more than 0.8 blocks per game for an entire season. “If I get a block a game and I play stalwart defense, I’d be satisfied.”
