You have to look at how Rondo gets his 3s. It's from defenders sagging, and doubling the post/Cousins. Someone on Reddit showed one of his biggest problems on offense
https://www.reddit.com/r/kings/comments/4dvk1c/not_sure_if_its_real_insight_but_here_are_some/
Defenders don't even bother to guard Rondo off the ball at the 3pt line A LOT of the times. I don't have anything to back this up, except my eyeballs.
Same eyeballs that tell me that Rondo is a terrible defender who just gambles in the passing lane instead of actually playing real man-man defense or recovering. This is why his steals are extremely high. Rondo is our biggest culprit in perimeter defense, which is why I agree with you on us needing more perimeter defenders. Rudy Gay is an average at best defender, and Ben/Curry is a lot better than Rondo currently is. This leads to me thinking we need to replace Rondo's defense.
I compare Rondo's defense to being a FS in football, when he should be the CB. The CB's job is to cover the WR AND intercept balls. The FS' job is to roam around until he can make an interception. (1st grade explanation)
Rondo needs to play like a CB where he has to both A) stay in front of his man and B) get steals. Instead, Rondo plays more like a FS where he decides he should only A) gamble for the steal.
I just don't know if you can successfully go forward with a core of Rondo-WCS-Cuz. WCS-Cuz is already a crowded front court. Rondo gets most of his baskets in the paint.
So if you're going to replace our SG with a defensive-type player, and our SF with a 3&D guy, it becomes extremely questionable if the team would even have a real #3 option in the starting lineup.
It just seems a lot easier if we decided to move away from Rondo, and start with a PG who can actually shoot and defend. Granted, there aren't a lot of them in FA, but *gulps* someone like Jeremy Lin would be a better alternative.
That reddit post is nonsense. They show 4 plays from one game and that's supposed to count as sufficient evidence that Rondo is killing our offense? That game was November 15th. Obviously nobody on Toronto respected Rondo's jumper 5 months ago but they have to now,
especially in the corners where he shot 43% this season. And that was also a game that we won 107-101 against the second best team in the Eastern Conference this year. Anyone who is scouting Rondo for next season has to acknowledge that leaving him wide open in the corners is probably a bad idea. He shot a better percentage from three this season than Mike Conley, Isaiah Thomas, Reggie Jackson, John Wall, Jordan Clarkson and D'Angelo Russell, Deron Williams, Jrue Holiday, Goran Dragic, Kyrie Irving, Russell Westbrook, Brandon Knight, Jeremy Lin... the list goes on. Are all of them off the table too if we want to put Cauley-Stein in the starting lineup?
If you only want to look at shooting stats for tightly contested jumpers, a whole lot of players are going to look terrible. Usually taking and making open shots is called smart shot selection. I don't know when floor spacing supposedly became the number one priority for every player on the floor, but I'm old school enough to think other skills are valuable as well and there are maybe 5 players in the league who don't have a significant weakness somewhere in their game. Maybe we're not a top 5 offense without a volume shooter at starting PG, but then again maybe we could be. We were this year. And if our defense gets a lot better we don't need to be.
Speaking of which you spend the bulk of your post talking about defense which, okay, fair enough. All Rondo discussions eventually circle back to there. "He can't shoot" and "he's hunting assists at the expense of the team" are both just stepping stones on the path to "he's clearly the worst defender on the team" and all three of them are equally lazy and inaccurate arguments. I'll grant you that Rondo's defense has been poor much of the season (not worst on the team poor, but I digress...). My point all along has been that you don't expect your starting PG to be a defensive stopper anyway. And Rondo is getting us extra possessions with his steals and rebounds. Your analogy about the defensive secondary in football is an apt one but I'm not sure you applied it correctly. Let me take a crack at it....
The reason you have different roles in your secondary is because the other team can run the ball or pass it, fair enough? So you have your cornerbacks to guard against the long ball, you have your strong safety to help stop the run or short yardage pass, and then you have your free safety to read the quarterback and get themselves in position to make a play on the ball. I'm a relative newby when it comes to football so I may be missing something important. But the way I see it, you can't very will defend a play with just speedy cornerbacks or hard-hitting safeties, you need both. Similarly, a smart basketball coach can design a defense to take advantage of multiple skillsets. Cousins is tough to move in the post but can't really get off the ground to defend shots in the air. Cauley-Stein is long armed and quick on his feet but not strong enough to hold position in the post. On the perimeter you've got guys who excel at face-guarding the ball, guys who excel at denying passes to their man, and guys who excel at anticipating passes and getting in position to deny them or intercept them. You can't very well do all of them at once so it's probably in your best interest if you have a variety of different skillsets and a gameplan that allows all of them to fill a role. You wouldn't want all of your defenders to be identical because that would leave without key skill areas.
So looking at next season, I'm only worried about Rondo's defense to the extent he shows a tendency to coast or opt out of defensive plays when he feels like it. Whoever the coach is next season they need to nip that in the bud real quick. And I don't think it would be that hard -- Rondo plays with a lot of pride. He's been selected to 4 all-defense teams in the past. Rub his nose in it until he gets pissed off and shows you he can play defense when he wants to. And then tell him he needs to play like that every game. Just simply stating the D word and expecting it to happen on it's own is not enough. But as for everything else, I'm not worried about his tendency to sit off the ball and play passing lanes or leave his man to crash the boards because a capable defensive unit would turn those into strengths not weaknesses.
For those other two spots in the lineup, I want the defensive stopper at SG not SF because a great defensive 2 guard can also guard
most of the PGs and SFs in the league. Also, the SF role has changed a lot in the last 10 years. It's probably the toughest spot to fill in a starting lineup. They have to be able to slide down to the 4 and guard shooting bigs and they have to be able to switch onto speedy wing players off pick and roll action. And then you've got a number of 6-8, 6-9, 6-10 scoring specialists who will back you down and shoot over you if you can't body them up and hold position. It calls for a completely different defensive skillset and I don't think you want a stopper so much as you want a high-energy player who's willing to work hard to at least contest shots and fight for rebounds in the paint. Also, since you have to think about offense, I'd rather my best shooter start at SF than SG because then the other team can't guard them with a PG and you pull at least one wing away from the basket. Get me those 2 players, and I'll build an intimidating defense with Rondo there at the head of it.
