NEW YORK — After years of honing their basketball skills together, Brook and Robin Lopez are going their separate ways in the NBA.

The twin 7-footers who starred at Stanford the last two seasons were both first-round draft picks last night, with Brook going 10th overall to New Jersey and Robin 15th to Phoenix. They were the first set of brothers to be selected in the opening round of the same draft.

“It will be strange,” Brook said shortly after flipping a Nets cap on his head and shaking hands with commissioner David Stern. “I don’t know when the last time was, but you know, you pretty much knew it was going to happen. So, I’ve been getting ready for that and here it is.”

The brothers, sitting with family members to the side of the stage, embraced when Brook’s name was announced.

“It was great,” said Brook, who averaged 19 points and eight rebounds last season. “I was so happy to be up there. I was living a dream.”

Robin didn’t have to wait long for his moment, but had a tough time getting his Suns cap over his thick curls — causing a few laughs from the crowd at the Theater at Madison Square Garden. After averaging 10 points and five rebounds last season and blocking 156 shots in two seasons, he’ll give the Suns a backup for Shaquille O’Neal.

“That will be a new experience,” Robin Lopez said. “I know I’ve called myself tough before, so I guess this will really put it to the test. And whatever doesn’t kill me, will make me stronger, as Kanye West says.”

The Nets have some previous experience with having a twin from Stanford on their team. Jason Collins, who starred with the Cardinal with brother Jarron, played for New Jersey from 2001 until he was traded to Memphis in February.

The two sets of twins became friends when the Lopezes’ older brother, Alex, played in the same Los Angeles summer league as the Collins brothers. The Lopez brothers followed them to Stanford — and now to the NBA.

“We pretty much stayed friends and the relationship continued through college,” Brook said of his relationship with the Collins twins. “To this day, they are just sort of mentoring me and we stayed in contact the whole time.”
