Can the Gotham Ballers beat the Knicks?

Former Knick Al Harrington won’t go that far, but thinks the new Champions Basketball League product will serve as summer itch for NBA-starved fans.

The concept of the upstart 16-team semi-pro league to debut in July has changed over the past year. Instead of dawning as an over-30 league for former NBA players, age is no longer a requirement. The only résumé requirement is being on an NBA training camp roster sometime during the previous three years.

Gotham’s roster is not yet complete, but Harrington is expected to be joined by ex-Knick and Net Kenyon Martin, ex-Sun Shawn Marion, Brooklyn product/former Pacers point guard Jamaal Tinsley, ex-Knick Renaldo Balkman, Chris Smith, J.R. Smith’s brother who had a cup of coffee with the Knicks, and Anthony Mason Jr., son of the former Knicks tough guy who played at St. John’s.

According to a league source, Gotham is recruiting ex-Knick point guard Nate Robinson, who currently is lobbying to join the Cavaliers.

“It’s quality — getting guys who are in shape and still passionate to play basketball, guys who are going to take it seriously,” Harrington told The Post. “At the end of the day, we’ll put on a real good product out there at a time in the dead of summer when nothing’s going on as a supplement. It should be right at the level of the D-League.”

But with a lot more name recognition. Gotham will play its two-month season at the newly remodeled Nassau Coliseum as well as Barclays Center. The Nets may step into a managerial role for Gotham.

The 16 teams are owned by the league for now. But Gotham is in the process of having fans be able to buy shares of stock in the franchise. Part of the player’s salary also will be stock options.

In an attempt to market to kids, fans will be allowed to take photos with the players before and after games. Ticket prices will be around $35-$40.

“That will have a huge impact, having former All-Stars with name recognition definitely helps this league,” Harrington said. “We’ve rounded up guys who are still in great shape and have basketball left.”

Harrington, the Jersey native who played for the Knicks from 2008-10, played professionally last year in Australia, but only for a month. Can he make an NBA roster?

“Of course I could,’’ said Harrington, 36. “But probably for 50 games and playoffs.”

Harrington said he is “pretty close’’ to being in game shape, but will have a tough time keeping up in practice with Marion.

“Shawn is one of the guys forever will be in shape no matter what,” said Harrington, who will make a league promotional appearance at the Garden on Friday during the Knicks game with the Hornets.

Walt Frazier and Earl Monroe have lent their names as Gotham’s team presidents. Former Syracuse star and former Knicks first-rounder John Wallace will be head coach. Wallace never has coached.

“That’s the cool thing about the league, it’s giving a chance to guys who still want to be connected to the game but haven’t had a chance,” Harrington said.

The Champions League organizers believes it will fill a void.

“We saw an opportunity to play in established NBA markets during the summer months, because there is no nationwide competitive men’s basketball league for hoops fans during that time,” said Carl George, CEO of the CBL. “We’ve found that fans of basketball love to watch the sport all year round, not just during the season.”

And who knows, after the disasters the Knicks and Nets have become, the town may finally have a winning men’s basketball team.

“Our team is built very nicely to be successful,” Harrington said.
