The opening Euroleague regular season game of qualifier Krka Telekom Novo Mesto of Slovenia had all the makings - and all the drama - of a neighborhood rivalry as neighboring Zadar of Croatia came to town on Wednesday. Zadar left town with the prize, too, a miraculous comeback from 20 points down in the second half to win it 91-94 on a three-point buzzer-beater by Marko Popovic, the 19-year-old son of new coach Petar Popovic. Zadar was down 60-40 just after halftime and climbed all the way back to forge and 81-81 tie with 5 minutes to play. But a tie did not become a lead. Krka broke a two-minute stalemate with five quick points that seemed to doom Zadar, down 86-81 near the two-minute mark. Two free throws by Popovic and a follow-up fastbreak my Davor Marcelic cut four points away from the deficit, however, and Rumeal Robinson put Zadar ahead finally with 1:39 to go. But Krka wasn't done. Jaka Lakovic raised up and nailed a three-pointer to give back the lead to the locals, 89-87. Ime Oduok got the tie again for Zadar underneath, then turned around and blocked Mate Skelin at the other end. Marcelic put Zadar up with a layup with 30 seconds to go, but with 9.1 seconds left, Krka tied. With the fianl possession, Zadar got the ball to the youngest player on the floor, the coach's son who wavered in signing until just recently, such were his offers to play college ball in America. Popovic raised up and let it go. All net. After a season of coming close all last season, Zadar wins its first in 2001-02. For one night at least, Zadar stands alone at the top of Group C.
