Alex Caruso and the OKC Thunder agreed to a contract extension Sunday night. Afterward, Thunder rising star big man Chet Holmgren shouted out the defensive-minded veteran via a two-word social media message. Acquired from the Chicago Bulls in exchange for fourth-year guard Josh Giddey in June, Caruso entered the season on a $9.9 million expiring contract. However, amid his high-level early season defensive impact, OKC wasted no time locking down his services long-term.Per ESPN's Shams Charania, a day after Caruso became extension-eligible on Saturday, he inked a four-year, $81 million contract extension. The deal locks the two-time All-Defensive team selectee up through the 2028-29 season. Charania added that Caruso ranks "top five (in the NBA) in deflections, field-goal percentage allowed as a contesting defender and points per direct pick allowed as a ball-handler defender." Thus, the franchise's decision was seemingly a no-brainer. Shortly after the news broke, Holmgren shared Charania's report to his Instagram stories, noting in his caption that his teammate successfully secured the bag."Money talks," Holmgren wrote.
