I'm not worried in the slightest. McNair has been extremely consistent in his intentionality with any move he makes with the Kings. It's very much the Morey tree where you're not making moves to just make moves, but only striking at the right times. Honestly, he didn't bring in a whole lot the first 2 seasons outside of retaining Holmes (good move, at the time), minor trades/FA pick-ups for back-end rotation players and making his draft picks. Then just turned on the turbo jets in the past year with the Domas trade, Monk FA signing, Huerter trade, Brown his first coach hiring, etc.
I mean, just look at the dialogue after the deadline about how pissed everyone was that he didn't make any substantial moves and that we'd fall behind in the playoff race. Maybe even fall all the way to the play-in. And the Kings have responded with an 8-1 record post-break.
