The Mavericks’ “biggest concern” is Cooper Flagg’s injury

Doc Flagg had to miss representing the Mavericks during All-Star weekend, there’s no denying that the team will take it cautiously, as he’s a player that will be built around for the foreseeable future. As Stein notes, the “bigger concern” for Dallas is “nurturing” the 19-year-old with a team that has lost nine straight heading into the All-Star break, which at this point has led to a 19-35 record.

“The bigger concern for the Mavericks — provided, of course, the injury doesn’t get worse — is that Flagg will be nursed through the ongoing 19-35 losing season,” Stein wrote. “Dallas has lost nine games in a row, which is surely the longest losing streak of Flegg’s basketball career and definitely ranks as the franchise’s longest since the 15-game stretch in 1997-98.”

In any case, it remains to be seen when Flagg will return, as the Mavericks are 12th in the Western Conference, heading into their first game after the break on Friday night against the Minnesota Timberwolves.
