One night, he's scoring 38 points on Kevin Garnett. The next, he's ripping down more rebounds than the other entire team.
   
Then rookie phenom Amare Stoudemire suits up against the Jazz -- and suddenly, Superman is tripping over his cape.
   
Stoudemire, the NBA's latest straight-out-of-high-school sensation, may be collecting accolades around the league for his meteoric rise -- "You see someone like him every 15 or 20 years," assessed teammate Stephon Marbury -- but the Jazz, who face Stoudemire and the Suns for the third time tonight in America West Arena (6 p.m., KJZZ), could be forgiven for wondering what the hubbub is about.
   
Could be -- but they understand, too. Despite a couple of so-so outings against Utah, both Jazz wins, Stoudemire has convinced the Jazz he's a potential superstar, too.
   
"He's a tremendous athlete," said coach Jerry Sloan. "He plays hard and he's fun to watch because he goes after the basketball and he's not afraid to stick his nose in there. He doesn't seem to be intimidated at all. . . . They've got a wonderful young player."
