Bailey has missed only four games in five years because of injuries, playing all 82 last season.Mike Brown, No. 40, forward-center, 6-10, 260, George Washington, 25, third year - Brown was officially acquired from Charlotte in a trade for Kelly Tripucka in June.

Brown played impressively this summer in the Jazz's rookie camp and Utah Pro-Am Summer League, raising hopes that he will become an important two-position reserve this season.

Billy Donovan, No. 31, guard, 5-11, 175, Providence, 23, second year - Donovan stayed with the Jazz through the exhibition schedule last fall before he and Eddie Hughes were waived as the Jazz reached the 12-player limit.

Darrell Griffith, No. 35, guard, 6-4, 195, Louisville, 30, ninth year - Griffith's last appearance of the 1987-88 season came March 5 against San Antonio; after that, he was sidelined for the season and had knee surgery March 23 . . . He averaged 11.3 points and about 43 percent from the field in 52 games in his least productive pro season, but hopes to bounce back from the injury and resume his shooting and scoring role again.

Bobby Hansen, No. 20, guard, 6-6, 195, Iowa, 27, sixth year - Hansen started 21 games in one stretch last season, but spent the next two months coming off the bench before Kelly Tripucka and Darrell Griffith were injured.

Because of limited activity in the middle of the season, his regular-season scoring average was only 9.6, but he shot almost 52 percent from the field and continued to play solid defense - especially against Magic Johnson in the Jazz-Lakers playoff series . . . Two Hansen-organized benefit games in Iowa have raised more than $100,000 for college scholarships for children of farmers.

Eddie Hughes, No. 25, guard, 5-10, 164, Colorado State, 28, second year - Hughes finally reached the NBA last March when he was signed to replace the injured Darrell Griffith.

Bart Kofoed, No. 11, guard, 6-5, 205, Kearney State, 24, second year _ Kofoed suffered a stress fracture in this foot during the early moments of the first game in the Utah Pro-Am Summer League in August and will miss most or all of training camp . . .

Karl Malone, No. 32, forward, 6-9, 256, Louisana Tech, 25, fourth year _ The Mailman really exploded in his third NBA season, averaging 27.7 points and 12.0 rebounds and leading the West in scoring in the NBA All-Star Game in Chicago with 22 points . . .

Jeff Moe, No. 30, guard, 6-3, 195, Iowa, 1G22, rookie _ The Jazz's second-round draft choice, Moe can play either guard position but will probably see most of his action at off guard during training camp with Bart Kofoed injured . . .
