This is partly the nature of the NBA. The players get paid way more than the head coach in almost every case and they also tend to have more job security too. Which means if you have DeRozan, LaVine, and Monk on your team as a head coach you have to play them their 30 mpg. The starting/closing thing is almost inconsequential -- they're going to get their minutes and if they're not winning those minutes than you're better off getting them off the roster. That or you build your entire organization around a head coach and a system and you make sure your players know that they are secondary to that. Which only works if you're winning... so here we are back in Catch-22 land again.
Personally, I like the idea of doing just that and going after Taylor Jenkins to build around the young players on the roster who actually give a rats *** and play hard.
It's fairly obvious that this thing needs to get blown up, so let's build a tough culture with a core of Keegan/Keon/Carter. No way Deebo wants to be on a rebuilding team, so trade him for what you can. Domas looks like he might also want out, but if he's down to be a vet presence on a rebuilding team I'm cool with him sticking around.
Zach we're stuck with, but he's got big Tank Commander energy, so I'm not worried about it. He leads us to the lotto a few times and then becomes a large expiring contract (although he does control the timing of this a bit with his player option).
Now obviously the FO needs to actually HIT on those trips to the lotto, and convince a coach like Jenkins to come here, but if we land a player that looks like a star, we'd already have the young tough team ready built around them. Use the cap gained by Zach's exit to get a few solid 2-way vets (like we've seen Detroit, Houston, and OKC do recently with great success). I feel like the path to a relatively quick rebuild is there.
But what do I know? I'm just rambling to kill time while we wait for the "Vlade re-hired!" announcement.
