Boston Celtics’ bench rescues shaky starters as Derrick White’s defensive brilliance seals a 129-119 win in Utah. Is it time for Joe Mazzulla to shake up the rotation again? John Karalis of Boston Sports Journal highlights key momentum shifts, breaking down White’s fourth-quarter heroics, seven-block performance, and the critical spark provided by Anfernee Simons and Luka Garza. Questions swirl around Jaylen Brown’s shot selection, the offense’s recent slippage, and a possible end to Jordan Walsh’s stint in the main rotation. Key topics include rotations under Joe Mazzulla, early shooting woes from Payton Pritchard and Sam Hauser, the strategic targeting of Jusuf Nurkić in pick-and-rolls, and Jaylen Brown’s streak coming to an end. Karalis analyzes how Derrick White’s rim protection is changing Boston’s defensive profile and asks what’s next as the Celtics prepare for matchups with the Sacramento Kings and LA Clippers.
