That combo only works if you have a playmaking small forward
Evans and McLemore might not have worked for 2-3 years (if then) and ensuring that we limit our endless sf search to a point forward. Evans was limited at seeing the floor and creating easy baskets. McLemore will probably get to where he needs to be but he played in the post for a good chunk of HS. There is a reason his handles and particular play making aren't where they should be right now. That backcourt would have some serious issues.
I think the super fandom here is creating a disconnect between what many would like to see happen and what actually needs to happen to create a winner. This team is not close and in need of just a few tweaks. Its a team, roster, and culture that's been permeated with losing, disfunction, selfish basketball, and unhappiness with the franchise, style of play and other teammates. That's hard to break up.
They want to give Cousins until February to turn it around and they probably won't extend him because: (1) they hope the max extension serves as a carrot to make him get in world class shape, perform, and behave better ... and then build upon his success; (2) if that happens, they will offer him a 5 year max on the first day of free agency and match any 4 year max offer. And if Cousins doesn't pan out, he's gone at the deadline and it's a complete blow up.
McLemore is an ideal 2nd banana for Cousins because he's a shooter, athlete, but not selfish about shots.
So that's the foundation for now. After that ... it's hard to scrub the selfishness, pockets of dislike, losing, and disfunction off the players and franchise. Like anything that's been neglected for a long period of time, you just have to throw a lot out.
To me, the disfunction, lack of trust, and lack of professional basketball players is what's affecting the defense, ball movement, and overall execution more than the individual players. When you play in a pickup game, at some point, if your teammates are hogging the ball, not executing on defense, and you keeping losing -- at some point, it really hurts your effort, shot selection, and sharing the ball. Here, that's gone on with some of the same crew for years. They don't trust each other. I bet a lot of them don't really like each other.
I would assume McLemore, Cousins, and Thompson will be here in 3 years. Maybe Vasquez if he gets a lot better. If IT wants to be a 3rd guard that works cheap, he might be around. Everybody else is gone in two years ... or maybe less. And that's needed. Get value when you can, but they need to bring in professional basketball players that will help remake and repair the culture. Thus, they tried to bring in Igudala and Calderon. They passed, so now it's stop gap measures with the same goal in mind and hope for luck in the lottery.
Vasquez was brought in because he's a professional, a good teammate, a willing passer that will radically change the ball movement and pump the ball to Cousins and McLemore. He's got upside and the Kings control his right via restricted free agency. He helps Cousins try to succeed and that's the gamble they've taken over Evans.
But more than that its about culture. At 8 million, the team might have held their nose and brought back Evens to see if they could make him fit. But at 11 he would have been an over paid SG that can't shoot, on a team with money locked into at least 3 SGs and only one they want to keep. More than that ... when Evans pounds the rock or smashes into a crowd, it undoublty affects the chemistry and morale of the team.
This has been a dysfunctional and poorly constructed team for at least 5 years. The front office felt that --- at that price - Evans had to go to address both issues. I'm fine with that.
But when you are scratching your head wondering with PDA is waiting for ... or why he's going to over pay some less talented vets on 1 and 2 years deal soon ... it's because he's trying to both completely change the culture and style of this team and make sure he properly pays the right pieces ... while the situation is a mess and people don't want to come. That's what I think. I'd bet that's what PDA thinks.
If you think this team is close and just needs a few tweaks, you may disagree. But this frame of mind might help you understand the moves.
