Sabrina Ionescu is joining Unrivaled as the new 3-on-3 league's final player

Sabrina Ionescu was thrilled to be part of Unrivaled — the new 3-on-3 league.

The Liberty star guard who helped New York win the first championship in franchise history earlier this year signed a historic agreement on Monday with the league. She'll join the Phantom BC that made a trade Saturday night to acquire Natasha Cloud.

"It was a huge decision getting me to play or not," Ionescu said in a phone interview Monday night. "I weighed out all my options and decided to do what’s best for me and my career. Being able to take part in a league that is the first of its kind with a historic deal and be on the ownership side of it is important for me.”

Ionescu said the league gave her some flexibility in her schedule if she needs to step away for a day or two. The NBA All-Star Game is on Feb. 16, which is in the middle of the Unrivaled season. The league has no team games during the NBA All-Star weekend. There's discussions of her potentially competing in another 3-point contest with Stephen Curry.
