Yeah, HB that drops 16-8-2 on 7 shots and 7-8 from the FT line absolutely deserves an extension. Where things get weird is if you resign him, the Kings are basically out of money for like the next 5+ years. Monk/Sabonis extension the year after, Fox is the year after that, then Davion/Keegan are off their rookie deals. So while I don't think we'll have a ton of cap, I'm pretty sure this is probably the last summer where the core we might be able to do something in UFA.
TD and Lyles have been great, but I think it's fairly unlikely we keep them past this season. So, ideally, you'd want to get some sort of return, but they've also been crucially important role players off the bench. Holmes is the biggest available "trade" piece, but you're basically hoping you can get someone to bite on an expiring for him at this point. It's tricky because McNair is now in a spot where the offense is so much better than initially expected, that you don't want to move any of the core pieces, but you're out of picks/trade ammo to find players that can fix the defense. Davion is probably the "most" expendable of the core guys, but on a team full of not good defenders, it doesn't really make sense to me to trade the only good one on the team. And as we saw tonight, he can just straight up win you a game with that defense.
