simmons isn't a great shooter, and that 19 year old point guard is 2 small. They need someone else 6'5 6'6 that can shoot 3s at 45% percent and defend like avery bradley.
the way the matchups are leonard takes durant, george takes klay, LMA takes green. You need someone big for curry that can score on his own, and you need someone athletic enough to stay in front of iggy and be able to make shots.
Dejounte is to small
Dejounte is 6 "5" with a 6 "10" wingspan but he is to small to play with Kawhi and PG
and the "someone big" for curry is...uh...the 20 year old point guard who is uh...bigger than steph curry...
They absolutely don't need someone who defends like avery bradley

...they already have kawhi who is arguably the best defender in the nba...Paul George is at worst one of the 10 best defenders in the nba...
Avery Bradley on this team would be overkill

...you going to have Avery Bradley... one of the 5 best defenders in the nba and between him and george night in and night out one of them is guarding the other teams 3rd best wing

...both of these guys specialize in making it difficult for even the best scorers in the nba to put up points and all of a sudden one of them night in and night out is guarding a guy who probably doesn't average 14 points a game...
Even against GS this lineup is probably overkill... Kawhi had his foot on GS neck for two and a half quarters playing with I'm having the second worst year of my career LMA, I can't dribble Danny Green, I played in 4 playoffs games before I scored a point manu, I'm playing in a WCF game and am not old enough to drink liquor Dejounte, and I was in the d league two years ago Simmons...PG by himself should be plenty good enough to pair with Kawhi with what the spurs already have or would lose and put around him...
Breh you out here trying to create the defensive version of the Warriors

...I'm a spurs stan but I do want to see competitive basketball

...I'm not trying to tune in to spurs games 3 times a week to watch Kawhi PG and Avery Bradley hold other teams not named GS to 30 % shooting from beyond the free throw line...I mean damn let the other team breath a little bit

... I mean as it is already we probably about to watch spurs vs gs in the WCF for the next 3 - 6 years anyway barring injuries...
