What happened: Tobias Harris has agreed to a two-year deal with the San Antonio Spurs, ending his second stint with Detroit. The Pistons had already moved to fill the void, agreeing to terms with free agent John Collins a day earlier. Harris arrives in San Antonio after two seasons anchoring a young Detroit roster.

Why it matters: Harris was less a scorer than a stabilizer in Detroit, a veteran presence credited with modeling professionalism for a rebuilding core led by Cade Cunningham. His exit tests whether the culture that lifted the Pistons out of the league's basement can hold without the locker-room voice that helped set it. Detroit now leans on its younger talent to carry those standards forward.

What to watch: Watch how Collins fits Detroit's frontcourt rotation and whether Jalen Duren's restricted free agency resolves as the Pistons reshape their roster around Cunningham.
