Im not sure what kind of super star teams you guys are talking about, but Barnes is pretty great as a 3rd option next to 2 stars (hopefully that's Fox/Sabonis). Super efficient, gives you elite spacing, has the ability to get to the FT line. Yeah he disappears sometimes, but that's why he's your 3rd guy; not the go-to or 2nd.
Let's math it out for a second:
17.3 PPG
63.2% TS
19.2% USG
10.7% TOV
10.6% AST
.530 FTr (massive for a non-elite option tbh.)
Let's go down the line where he "wouldn't" be a 3rd scoring option:
Suns-Booker the clear 1, but the rest of the team is pretty incredibly balanced. Cp3 and Ayton are good, but I think Barnes has actually been better than scoring than both the last 2 years. So anywhere from 2-4 on the best team in the league:
Warriors-Steph obviously, but once again gets pretty muddy
-Klay has not been good since coming back
-Barnes just straight been better than Wiggins too with his efficiency.
So once again, anywhere from 2-4 makes sense, especially if Klay doesn't return to form.
Grizzlies: Ja Morant obviously, but once AGAIN gets pretty muddy
Bane, JJJ are both pretty great compliments but I wouldn't call either just leaps and bounds ahead of Barnes. Numbers wouldn't either as Barnes is pretty far ahead of both. So 2-4 once again.
Jazz: Mitchell obviously, and yet again, we get muddy:
Bojan, Conley, Clarkson, Gobert. Once again, I don't know how you say he's behind all those guys this year with his numbers. Anywhere from 2-5 makes sense.
Mavericks: Luka obviously,
Here's where Barnes clearly would be the #2. Funny how that worked out, they'd love to get Barnes back.
Nuggets: Jokic obviously,
With Murray/MPJ out, Barnes would clearly slot in the #2 ahead of Gordon/Barton. You'd take healthy Murray and MPJ vs Barnes is pretty coin-flippy. So fully healthy, 3/4 option?
Twolves: KAT obviously,
Edwards/DAR aren't nearly as efficient, but have shown to handle a bigger USG role. Probably the first spot where he'd slot in as a 4th option next to stars.
Clippers: Not healthy, I think Barnes would be pretty close to their best offensive scorer. Maybe Reggie Jackson I guess over him? Norm Powell? I guess some preference, but can't say either Reggie or Norm are drastically ahead of Barnes. Obviously, he's behind healthy Kawhi/PG
Lakers: Slots clearly 3rd behind AD/Bron. Would be perfect compliment to them and the Lakers would kill to move Russ for him.
Pelicans: Slots behind Ingram and CJ. Do we include Zion? If not pretty coin-flippy between him and Jval. So 3rd/4th option.
2 very interesting things really stand out:
1. Barnes is really freaking good and we shouldn't underappreciate how elite he's been the last 2 years scoring/spacing
2. You need a lot of good offensive players to compete as well as a stand-out top 10 offensive player. Makes me want to go get a Malik Monk type in the off-season even more for better offensive depth.
