He had been offered up in trade packages as part of the Lakers pursuit of Anthony Davis and spent the hours before tipoff against the Celtics at TD Garden watching the clock and scanning social media. “That was a weird day,” Kuzma said Monday. “Before trade deadline it was weird, you knew something was going to happen but you didn’t know what was going to happen. But like after the deadline it was like you’ve got to play a game.”
