The New Jersey Nets will bring up the rear of the division, but they, too, are greatly improved. First-round draftees Mike Gminski and Mike O'Koren are young players to build a dream on. O'Koren, a forward, could pass as the twin of Philadelphia's Bobby Jones in physical appearance, style of play and college background ( North Carolina). "He understands the game better than most rookies," says Nets Coach Kevin Loughery. "Reminds me of myself." Gminski, 6'11", should convince doubters that he's no Kent Benson, another big, white All-America center who has been a disappointment since he entered the league. Gminski is an excellent shooter who needs to learn defense. Loughery is upset that New Jersey let shot-blocker George Johnson sign with San Antonio. "You just can't lose your starting center in this league," he says. "Now Mike will have to jump right into the fire." If Gminski can take the heat, the Nets won't do badly at all. Former Cavalier Clarence (Foots) Walker joins eclectic shooter Mike Newlin in the backcourt. At small forward, O'Koren and Jan van Breda Kolff will share the time opposite Maurice Lucas, who is determined to prove that his reputation as the league's best power forward did not come just from playing next to Bill Walton in Portland for two seasons.
