It's been a frustrating stretch of the season for Jazz veteran Raja Bell. He acknowledges it. After ex-coach Jerry Sloan resigned on Feb. 10, Bell missed three games with a calf strain. After returning, he scored five points on 1-of-10 shooting at Dallas and Indiana. Bell seemed to regain his stroke during Saturday's 120-116 loss at Detroit, where he made 6 of 9 shots and scored 14 points. On Monday night, however, Bell scored two points in 27 minutes in the loss to Boston. He made 1 of 4 shots. "I'm frustrated we lost," Bell said before practice Tuesday. "Any time we lose, frustration comes along with that, especially at this point in the season." Asked about his limited impact on the Jazz's offense, Bell replied, "I said when I came here I would do whatever people asked me to so. And that hasn't changed.
