And they let Alex Caruso walk, and replaced him with more bad defenders sans Bazemore. Between trading away KCP, Kuzma and Harrell, and letting Caruso and Schroeder go, and replacing them with Westbrook, Anthony, Bazemore and Monk, how exactly did they fix their 3-ball problem?
KCP: .410 3P% on 5.5 3PA per 36 minutes
Caruso: .401 3P% on 3.1 3PA per 36
Westbrook: .315 3P% on 4.1 3PA per 36
Anthony: .409 3P% on 6.9 3PA per 36
Bazemore: .408 3P% on 5.0 3PA per 36
Monk: .401 3P% on 8.7 3PA per 36
If you take out Harrell (a PF who can't shoot, so didn't shoot from deep) and Westbrook (a PG who can't shoot, but won't stop shooting from deep), LA has only added one extra shooter thus far, considering who its lost and added.
Let's look at Defensive Box Plus/Minus to get an idea of how these guys contributed on the other end of the floor. Leaving Harrell out of this one because he's the only non-guard/wing, thus he's guarding different players in a different role:
So the Lakers added some extra perimeter shooting after replacing what they lost, and appear to have gotten worse on perimeter defense. It'll be an interesting year indeed.
And if no pure shooter is ever washed up, why isn't Kyle Korver on somebody's squad?
EDIT: Forgot to mention that all of the stats I listed come from basketball-reference.com.
They did not let Alex walk, he was pretty much going to leave anyway because the money was on the table and he would be stupid not to take it. He already have a ring, no need to chase another. The clear point is that during the playoffs none of the people that left actually allowed the Lakers to win since they could not get pass Phoenix.
Those stats look nice on the macro but wins are what matter and when AD and LB were hurt, the wins were not coming. The team struggled mightily during those stretches and their shooting was terrible. Who cares about their + - on Defense if the team cannot score points. Its evident that the current roster was not doing the job so shake it up.
As for defense, I believe its more to do with the defensive scheme then the individual players. We will see if scoring more is better than losing some defensive pressure.
As for Kyle Korver, here is your answer. Looks like its him that does not want to go back probably because well, its time to retire. https://nba.nbcsports.com/2021/02/05/kyle-korver-will-you-return-to-the-nba-this-season-i-dont-know/
