Sam Smith of Bulls.com writes that a trio of Portland Trail Blazers guards all rank among the NBA's biggest disappointments in 2011-2012. ------------------------------ Jamal Crawford/Ray Felton/Wes Matthews: All are having career or next to career low scoring and shooting seasons, which basically explained why Nate McMillan didn’t finish the season. As for Jamal, he never was a great shooter. But his overall average is his lowest since his rookie year and his threes are lowest ever for him at 31 percent. His overall scoring average is his lowest in 10 years. ------------------------------ -- Ben Golliver | benjamin.golliver@gmail.com | Twitter
