As MacMahon noted, "Sources told ESPN that Patrick Dumont, who just finished his first year as the Mavs' governor, considers the opportunity to be in position to draft a generational talent like Flagg a 'gift.' While Dumont has given Harrison great leeway to run basketball operations, the governor has final decision on all personnel matters."

The Mavericks plan to select Cooper Flagg and will not entertain the possibility of trading away the No. 1 overall draft pick for a proven superstar, sources told ESPN.
