Deron gets first Barclays points

Deron Williams is the face of the Nets. Now he also will go down in history as the first player to score in the history of both the Brooklyn Nets and Barclays Center.

After Brook Lopez won the opening tip from Raptors rookie Jonas Valanciunas, Williams drained a 14-foot jumper from the left wing just 18 seconds into Saturday night’s 107-100 Nets win.

Williams finished the game with 19 points and nine assists.

* Though it was a monumental night for the Nets franchise, the same could be said for Keith Bogans.

Bogans was active for the first time since fracturing his left ankle, as well as completely tearing his deltoid ligament, after an awkward landing in a game against the Pistons on Feb. 8.

“This is one of the best feelings I’ve had in a long time,” he said before the game. “After all I went through, getting back out on the court I’m just excited. I feel like a kid again. … I’m almost overexcited.”

Coach Avery Johnson said he would limit Bogans’s minutes — the reserve didn’t see the floor last night until late in the game — as he continues to deal with lingering soreness in his right knee throughout training camp.

But considering everything he had gone through to make it back on the court from an injury that, at one time, he thought could be career-threatening, he has no trouble being patient.

“That’s going to happen,” he said. “I’m just trying to get back to 100 percent, get my body to feel right. … That’s the main thing.”

* The Nets unveiled their Marvel Comics-designed mascot, the “Brooklyn Knight.” The mascot made a grand entrance before the game, descending from the rafters of Barclays Center to the court during pregame introductions.

All fans at the Nets’ home game against the Magic will receive a limited edition Brooklyn Knight trading card.

* It was the third straight season-opening win for the Nets, who beat the Wizards in Washington last year and the Pistons the year before.

The victory also drew the all-time series between the two Atlantic Division foes to an even 33-33.
