Let me preface this by saying that I'm a fan of McNair. But it's a pretty low bar to be the best Kings GM since Petrie. So far the quick summary of McNair's tenure is:
- Solid if unspectacular first round picks that skew older and more NBA-ready: Haliburton, Mitchell, Murray.
- No real success to speak of with 2nd round picks unless Queta becomes a rotation player in the future
- One major trade - Haliburton, Hield and Thompson, for Sabonis, Lamb, & Holiday plus a SRP
- One other significant trade - Harkless, Holiday, and protected FRP for Huerter
- Several minor trades - some good (SRP for Terance Davis), some bad (Delon Wright for Tristan Thompson), most pretty inconsequential (Bagley for DiVincenzo, Cory Joseph and 2 SRPs for Delon Wright, Bjelica for Harkless, the rights to Hardy for future SRPs etc)
- One major signing in Malik Monk
- Lots of minor signings (Whiteside, Metu, DaQuan Jeffries, Glenn Robinson, Damian Jones, Alex Len, re-signed Holmes, Keon Ellis that are overall positive, and a few that were clearly made for Brown (Moneke, Okpala, Dellavedova, keeping Metu)
Not an amazing track record, but he's gradually increased the talent level. As long as he and Brown have a good working relationship I think you need to re-sign him just to have the consistency and continuity that the Kings have lacked since Petrie and Adelman.
I can understand people who argue that McNair hasn't done enough and that he's building a team that can make the playoffs but will never win a championship. There's some validity to that criticism, at least as things stand now. But for me, the Kings are fun again. That's all I want. And if he can continue to have that be the case, I'll be happy.
