While the BIG3 league is made up of former NBA stars who are past their primes, the players are confident they could still compete at the highest level.

When Stephen Jackson was asked Sunday if a team of the top BIG3 players could beat an NBA Summer League squad, the 14-year veteran took it a step further.

"I honestly feel that if you got the top 10 guys here, we could beat an actual NBA team," Jackson said in a pregame press conference, via Fox Sports 1. "Not just the summer league, we'll beat an actual NBA team."

Kenyon Martin agreed, although BIG3 coach Gary Payton noted the players would likely need a month to get into "great, great shape."

Jackson, who hasn't played in the NBA since 2014, also told reporters in Tulsa he could still help the Oklahoma City Thunder.

"I won't be like [Andre] Roberson," he said, per Brett Dawson of the Oklahoman. "They won't be hack-a-Shaqin' the small forward."

There are certainly a lot of notable names competing in the BIG3. Allen Iverson is arguably the main attraction, while Chauncey Billups, Mike Bibby and Jermaine O'Neal have all had success in the league.

Just about every player is a few years removed from last playing in the NBA. Al Harrington led the BIG3 in scoring through two weeks and he is 37 years old.

While a matchup between BIG3 stars and NBA players would be interesting, those currently in the three-on-three league might be a bit overconfident.
