Cooper Flagg scored 31 points and grabbed four rebounds in defeat.

After the stunning Luka Doncic trade, many wondered what Nico Harrison’s future as general manager of the Dallas Mavericks looked like. Before the 2025-26 season begins, Harrison received a vote of confidence from a key figure.

While all the attention was being paid to Cooper Flagg, former Auburn guard Miles Kelly was looking to show his capabilities on the basketball court. He scored 17 points in the Mavericks first game of the Las Vegas Summer League and helped his team to an 87-85 win over the Lakers.

The Dallas Mavericks' offseason has been defined by selecting Cooper Flagg with the No. 1 overall pick in the NBA Draft. However, they haven't done much outside

Kelly supplied 11 points (3-8 FG, 2-6 3Pt, 3-3 FT), two rebounds, two steals and one block over 27 minutes in Saturday's 76-69 Summer League loss to the Spurs.

According to recent comments from Jovan Buha of The Athletic, the Mavericks may have a chance to trade for him. According to Buha, he's uncertain if the Lakers and James have a good relationship going right now.
