Nothing personal, says Jose Calderon.

In fact, the former Knicks point guard now with the Lakers admits that his role perhaps got too large the past two seasons. He credits team president Phil Jackson for doing the right thing in obtaining Derrick Rose to man the position.

Calderon was traded on June 22 in the Rose package to the Bulls. In turn, to open cap space for the signing of Dwyane Wade, the Bulls traded Calderon to the Lakers.

On a two-day leave from Spain’s Olympic Team, Calderon flew into Los Angeles Thursday for physicals. He is currently Olympic teammates with new Knicks center Willy Hernangomez.

In a phone interview with The Post, Calderon, who’ll be 35 in September, said he wished he could’ve remained as Rose’s backup but realized the Knicks needed more pop at the starting position.

“It’s something they needed,’’ Calderon told The Post. “Like I said, I was ready for a different role and I was ready for a different role the last couple of years. Maybe there wasn’t the player to put ahead of me.

“I always said I wasn’t the one putting me in the starting role or playing me 35 minutes. It could’ve been a guy like a Derrick Rose and I would’ve been the backup point guard. It’s a tough position to play. You have to know your strengths and weaknesses. I’ve been in the league 12 years and I know what I do best or not do as well. It’s nothing personal. It’s what the team needed. Hopefully it will work better.’’

Calderon now sees himself as a backup for the Lakers, who boast young studs D’Angelo Russell and Jordan Clarkson. He calls it “a good mix of young players.’’

Calderon is a pass-first, shoot-last point guard whose 3-point prowess (41.2 career percentage) and teamwork will make him a useful part at Staples Center.

Jackson alluded to Calderon as under-appreciated, saying Knicks fans “didn’t warm up’’ to the classy Spaniard. His perimeter defense declined after the 2014 trade, but Calderon believes it became unfair to compare his Euro style to the new American brand of scoring point guards.

“They try to compare all the time,’’ said Calderon, who averaged 7.6 points and 4.2 assists in 72 games — all starts — last season. “You can’t compare my numbers to the other point guards. I’m a different kind of player — if you like it or not. I play a certain way and played like that for a while. Maybe you want a point guard to shoot 20 times, I like more to pass the ball and do my job running the team. This guy only scores six points, another guy scores 30, but I’m not that kind of point guard. You can’t compare my game to others.’’

According to Jackson, Anthony, in his exit interview, lobbied for a new starting point guard. Calderon holds no grudges.

“I heard from Carmelo the next day — he’s a good friend, been my teammate for two years,’’ Calderon said. “I wish everything will be better. Because the first year we all know what happened [17 wins] and last year we expected something different but it didn’t happen.

“They can make the playoffs. They got great players — let’s see how they play together. I’d be real happy for Melo and [Kristaps Porzingis].’’

Calderon says he’s nowhere near the end despite having just one year, at $7.6 million, left on his contract.

“I would like to play 15 years in the league, so hopefully three more years,’’ Calderon said. “I played 30 minutes [28.1] last year. I don’t think I’ll play that much ever again, so I’ll be able to play more years. I’m happy and comfortable here.’’

Calderon had hoped to be in New York with Hernangomez, a 2015 second-round draft pick. But they are together on the Spanish national team for now.

Hernangomez could get cut from the final 12-man roster if Marc Gasol is cleared to play. Calderon likely will be Ricky Rubio’s backup as Spain is a favorite to reach the gold-medal game in Rio for the third straight Olympics.

“Hopefully we can get to the final again and play the US,’’ Calderon said.

Regarding Hernangomez, Calderon gushed, “He’s quite talented. He played for Real Madrid, a really good team. He’s young and needs time for sure. I like what he can do — run the floor, pretty mobile, moves really well. The NBA is different. You never know what’s going to happen but I think he’s a good player.’’

Calderon has advised Hernangomez on the hot spots of New York. He’ll also have an instant buddy in Porzingis, his former Seville teammate.

“The good thing about it is he’s pretty close to Kristaps, it will be easier for him to adapt and KP has another friend.’’
