The OKC Thunder topped the Dallas Mavericks in their 2023 Vegas Summer League opener. Cason Wallace set the Oklahoma City Thunder fanbase on fire during the first half of his NBA debut. The OKC Thunder rolled out a lineup many would call “unfair” with such a talent-rich Summer squad. Cason Wallace, Tre Mann, Ousmane Dieng, Jaylin Williams, and Chet Holmgren gave OKC four first-round picks, three of whom were selected in the lottery, and a play-in starting big man from a year ago on the Vegas floor. Unsurprisingly, as the game went along, the OKC Thunder eventually gained control and overpowered the Dallas Mavericks.
