Recently, NBA legend Paul Pierce talked about Flag in the "SPEAK".

Pierce said: "We know that Avery Johnson may still get money from Dallas. No one said that the team will be better after missing players who are the first team of the All-Squad and MVP candidates every year. Doncic had brought Dallas to the finals before. We don't know what kind of player Flag can be. I know who Doncic is, and the opponent will be afraid of him. Everyone knows that, as far as we look at it, there is nothing good to compare with Doncic and Flag."
