I was all for going hard after Ayton this year until we traded for Sabonis. I think Myles Turner was a better shooter than Ayton and that pairing didn't play well in Indiana. I doubt Sabonis and Ayton will be able to coexist on a team with rather suspect outside shooting, especially when you are trading away your best catch and shoot player on the team. I would much rather invest money into a player like Bobby Portis who is not only a strong defensive player, at the 4, but also a good 3pt shooter, reasonably good rebounder and hard nose tough guy who can inject some much needed grit to this team. Would also take PJW and Chris Boucher. I would also potentially take a flier on Mo Bamba (who may be able to play next to Sabonis given his outside shooting)
Easiest senario (money wise) would be a S/T involving Holmes for PJW and Cody Martin (on a new deal for 5-6M/ for 3 years). Then resign DDV, Damian Jones and pick up option on Lyles.
Fox/Mitchell
DDV/Martin
Barnes/Lamb/Martin
PJW/Lyles/Barnes
Sabonis/Jones/Len
Then also add in your FRP.
My counter-argument is Sabonis-Turner actually did have some success prior to the Nate Bjorken season where a very promising Pacers roster was just decimated in 1 1/2 seasons. After they fired Nate McMillan
48-34 in 18-19
Turner-28 MPG
Sabonis-24 MPG
45-28 in 19-20
Sabonis-34 MPG
Turner-29 MPG
And if Sabonis is going to be one of your cornerstones, you're more than likely going to have to commit to a unconventional team build. Unless you find the unicorn 4 (which Chet/Jabari can actually be), like a JJJ, you either go for the all offense build with 4 out, or you get Sabonis a rim protector and play him at the 4. Ayton is just levels above Turner too, which should matter in the evaluation to pair them.
A big reason I've been on the Hartenstein train is he can be that great rim protector with some really good offensive talents as well outside of just finishing at the rim. Ayton is an incredible roll man, but I think he's one of the few bigs in the NBA with actual self-shot creation ability. With the Sabonis passing, I think you'd have a real match-up nightmare defending 2 "big" bigs that can create their own offense. Would certainly force teams to rethink small-ball 4's against them.
Ultimately, I just care that a 24 year old stud player that should never hit the open market is likely going to be available. A talent deficient team shouldn't pass just because the fit isn't clear right away. You get out of the gutter with players like Ayton.
