Dallas is facing a significant setback as Kyrie Irving has been diagnosed with a torn ACL, ruling him out for the remainder of the season. This presents an opportunity for Spencer Dinwiddie, who is likely to become the Mavs' starting point guard. Currently only 22% rostered in Yahoo! leagues, Dinwiddie averages 14.4 points, 5.1 assists, and 1.2 steals over his 19 starts this season. He could fill the void left by Irving's absence and potentially aid fantasy teams struggling with injuries.

Elsewhere, Ja'Kobe Walter from the Toronto Raptors is stepping into the starting lineup in light of Gradey Dick's knee injury, showing promise with a strong performance in his debut. Atlanta's Caris LeVert, traded from Cleveland, is thriving with consistent scoring. Quentin Grimes of the Philadelphia 76ers is proving to be a key asset, posting multiple 30-point games this season. In the frontcourt, Zach Collins and Kelly Olynyk are both capitalizing on injury situations, making them valuable additions for fantasy managers.
