Fallout from Kyrie's knee injury: Irving's player option, injury timeline, tank for Flagg?

Kyrie Irving is officially out for the rest of the season after he sustained a torn ACL in Monday's game, and the Mavs' chances of getting healthy and making a run are officially doomed.

With the Mavericks' season virtually over, what will the team prioritize over the final 20 games of the season? Will they tank to improve their chances of getting Duke star Cooper Flagg?

And when is the earliest and the latest Kyrie Irving will return to the court? Will he actually be a Maverick? Will he now opt into the final year of his contract this offseason worth $43.9 million?
