Not exactly sure how Kemba and MKG form a better foundation going forward than CP3. MKG on the floor with any less than 2 respectable shooters is a disaster on offense and even if Paul isn't a top 5 player in a few years how much better do you think Blake looks as he tries to work from the elbows surrounded by a roster of players that can't shoot? There's no simply way in which they get better but teams have proven time and again how easy it is to get worse. Paul's game isn't predicated on athleticism and over the next 5 years there are maybe 4 point guards that realistically stand be better than him. I don't get how that justifies folding up for Kemba. Wing defense is an issue but it is exacerbated by Blake and Deandre's lack of smarts on that end.
The only time you can ever justify trading a star for parts is if things flat out aren't working and even then most orgs should be loath to even contemplate it. The thing is of the 3 max guys one is clearly not a star and as much as there's not really much else they can do, they're hamstrung the minute Deandre inks that contract. He's the weak link and whatever he gives you in rebounding and blocks doesn't measure up to a more filled out roster.
Their situation is painful but for now it's best they do nothing and see what shakes out with the new cap. Dealing Paul with no concrete plan or prospects of commensurate compensation would be folly.
Getting Walker, MKG, Vonleh and their
pick this year would be a better foundation moving forward since the current roster is already maxed out. By the time the new cap takes affect Cp3 will be 31 turning 32, they will have another wasted season behind them. That is why you trade him for players that can contribute now, a prospect and a lottery pick. That gives them a chance to stay competitive, with the potential of being even better when the young guys develop, again Blake and DeAndre are only 26, if their window shuts it's because CP3 has lost a step and at that point he's done. You say CP3's game isn't based on athleticism, and that isn't really true, he's one of the quicker PGs in the league and that isn't going to last another 5 years, this is a dude that had his meniscus removed so the window for him isn't as wide as you may think, all it takes is one lost step.
The problem isn't Blake and DeAndre's lack of smarts, it's the fact they are constantly being attacked so they are going to make mistakes. When you have JJ Redikk and Matt Barnes on the perimeter, your frontline is always going to be under pressure. Neither guy is a great defender, but the amount of times they're challenged per game just makes the problem even worse, Redikk was better this year but he's not a great defender by any stretch and Matt Barnes is just a turnstyle on defense.
Nobody can explain to me how this team is going to get better, this is the quote from today -
"We have to get this team more support," Rivers said. "With the contracts we're hamstrung with, it's going to be minimum deals for the most part. There are no big deals out there that we're going to make, most likely."
They plan on going after minimum salary guys in a year teams are expected to be willing to overpay to get wing guys

They've been together for 4 years now, it isn't working and the moves Doc has made in the past means they have no depth, no assets, no capspace and no way to really improve other than moving one of their main guys, or just waiting for the cap to increase. LeBron, Bosh and Wade had more support, were better players and almost everyone agreed that them breaking up was inevitable because of the fact they couldn't get better rotational players, yet the Clippers should stick it out?
