This is bull , not necessarily in the sense that your analysis of PATFO's reasoning is wrong. But there's no justification for it. I REALLY don't want to get into a situation where I can be perceived as rooting against Murray or whatever, but the D was WAY more than just him last year. There's a reason why Green and Anderson are having great defensive years as starters for teams near the top of the standings. If Pop thought just Murray was going to make up for not just those guys leaving but for DeRozan and Beli replacing them, he's off his ing rocker. As someone mentioned, Murray isn't Kawhi. You don't put yourself in a situation where he has to be the DPOY for your club not to be terrible on that end. I can't rationalize how "the plan" was to not have three-and-D wings when they had enjoyed so much success with those players. Like how is Murray, DeRozan, Green with Gay off the bench not better than Murray, DeRozan, Gay with someone like Cun coming off the bench?
Yeah, DeRozan will need a shooter or two next to him to succeed so long as he has LMA on the team. He's just not a good enough off-ball player to deal with two other guys taking touches. The only reason it sort of works with Gay is Rudy taking and making more threes.
I think Pop's gotta stick with Cun. He made that switch back to him because Rudy showed no ability at all to check Gibson. This isn't rare for Gay either. You can say what you want about net ratings or whatever, but Pop's never going to go for a scheme where a guy is just being backed down relentlessly like Gay was. The way Rudy played Taj was not acceptable. Maybe Bertans would have done better, but he's had his share of failures there. Yes, the team needs someone better than Cun, but they don't have anyone better. Barring a trade, they have to go with someone who at least tries on D and on the boards.
The team is at a crossroads. Their personnel is just not good enough. DeRozan isn't a good enough player to be the ace on a Western contender. Aldridge isn't good enough anymore to be a top second option. Gay isn't good/healthy enough to be a consistent third option. Their role-players have too many obvious flaws and not enough obvious advantages. The young players are too raw/injured/Derrick White to expect them to make a difference this year. They have two weeks (and two days) until the trade window opens up for Gay and Beli (and guys like Cun and Pon). I'd give the team those two weeks to demonstrate who they are. If they pull out of their tailspin and are a solid playoff team by the time that window opens, then you look to make something happen with Gasol and other ballast. If they don't show that, then you start seeing what you can get for some of these guys, with an eye toward a power-tank into a reloading year. If the wheels completely fall off, you don't even worry about that and just fire sale guys. This team was built wrong and is coached wrong. It reminds me of the 2015 Heat in terms of an organization trying to show it was better than it's former star and just failing.
