With last night’s game against the Bulls on the line, the Nets went to Brook Lopez three straight times. And, three straight times, Lopez came up empty. The result was an extremely disappointing 92-90 loss to an undermanned Chicago team in front of a sellout crowd of 17,732 at Barclays Center. “It’s tough, just because our team was playing so well through the majority of the game and I contributed a lot to how the final score ended up,” said Lopez, “and that’s definitely not something I’m happy with or proud of.” In a season full of milestones and highlights for Lopez, including making his first All-Star Game, the final minute of last night’s game — one that began with Lopez scoring 18 points in the first quarter — will be something he’ll do his best to forget. It began with the Nets getting the ball with 44.7 seconds left with a 90-89 lead after a Luol Deng jumper in the corner. The Nets chose to give the ball to Lopez in the post. But, after trying to back down Bulls center Nazr Mohammed, Lopez got caught in no-man’s land and tried to throw a pass to Keith Bogans that instead landed in the waiting hands of Bulls guard Nate Robinson. “I was looking through my options to where to kick it out to,” Lopez said. “I felt I didn’t really have [Deron Williams] or Joe [Johnson], so I tried to get it over there to [Bogans] and [it was] just a terrible play on my part.” After Robinson dribbled down and nailed a floater over Lopez to give Chicago a 91-90 lead with 22.7 seconds left, Lopez got a chance to atone for his previous mistakes. Williams, who was spectacular all night, finishing with 30 points and 10 assists, dribbled into the lane and found Lopez all alone under the hoop.
