Just to give the Dallas Mavericks a pretty quick glimpse of what kind of player they’d acquired, Anthony Morrow put on one of the most prolific shooting performances in the 11-year history of American Airlines Center. During a shooting drill at the end of Saturday’s practice, Morrow promptly loaded up his arm and converted 24 of 25 3-pointers in one amazing stretch. That type of shooting display is why the Mavs acquired the 6-foot-5 swingman in a trade with the Atlanta Hawks for Dahntay Jones on Thursday. “He’s money,” forward Dirk Nowitzki said of Morrow. “It’s like a little set shot, and he kind of like brings it up to his face. He gets it off quick, and if he’s open it’s going in. We already knew that.” While Nowitzki said Peja Stojakovic was the best pure 3-point shooter the Mavs have ever had, he ranks Morrow right up there next to Stojakovic. After finishing his first practice with the Mavs on Saturday, Morrow said he “couldn’t stop smiling” when he discovered the Mavs had obtained his services. He also will be on the court at some point at noon Sunday when the Mavs host the Los Angeles Lakers.
