Former Ohio State basketball star guard D'Angelo Russell has signed a 2-year, free-agent deal with the Dallas Mavericks.

The team announced that Cooper Flagg, the No. 1 pick in the 2025 NBA draft, signed his rookie deal with the Mavericks and that he will participate in the Summer League for the team. Dallas did not disclose the terms of the deal, citing team policy, but the deal is expected to be a four-year contract worth about $62 million.

As expected, Cooper is going to be in Las Vegas for at least the first weekend. Flagg is joined by the two undrafted free agents that the Mavericks signed following the second round of the 2025 NBA Draft,
