Cooper Flagg’s mom Kelly makes feelings clear on Nico Harrison firing

The Dallas Mavericks season has been a disaster so far. So much so that GM Nico Harrison has been fired nine months after the Luka Doncic trade to the Los Angeles Lakers. The fans are letting the team have it, including No. 1 overall pick Cooper Flagg’s mom.
The one bright spot lately has been Flagg’s play which includes his 26-point, nine-rebound game on Monday night in a 116-114 heartbreaking loss to the Milwaukee Bucks.
With the team just 3-8 and seeing what Doncic is doing with the 8-3 Lakers — averaging 37.1 points, 9.4 rebounds, and 9.1 assists per game — Mavs owner Patrick Dumont pulled the trigger on Harrison.

It’s clear what her feelings are about Harrison.
Here’s the scene the fan was referring to when P.J. Washington was trying to shoot free throws at home in the American Airlines Arena.

Cooper is averaging 15.0 points, 6.8 rebounds, and 3.1 assists in his first pro season out of the Duke Blue Devils.
It’s ugly in Dallas, but Flagg is the future. With Nico gone there will be less distractions for the team and more dunks like this from Flagg can be celebrated by the fans, including mom.
