The first thing before trying to go after Paul is to secure the front court in the event of a Pau trade/opt out. The easiest way to do that would be to have Dedmon opt in with the promise that he's bound to get a ton more with another year to show off his talent and with Paul feeding him. Maybe he opts out and re-signs for the new, much bigger room exception, but you'd like to keep that to fill out the rotation if possible. If you do that, stash Milutinov (but not the pick) and let the FAs walk, you have just under $20 Million to offer him. Honestly, that's a great ring-chaser contract. You do the trick with Dedmon, it's $23 Million, but again, you'd like to keep something back just to fill out the rotation.
Paul, Parker
Green, Murray, Forbes
Kawhi, Anderson
LMA, Bertans
Dedmon, (blank)/Lee/Pick
I'd probably want to bring Nikola over anyway and use the pick on a wing while also bringing in Hanga. Regardless, having Parker on the team is drag on resources, but it would be necessary to recruit CP. If you off the one-and-one, it could be enough to entice him into biting. Maybe something like:
Paul, Parker, Murray
Green, McLemore (room), Forbes
Kawhi, Anderson, Hanga
Aldridge, Bertans, Ojeleye (first)
Dedmon, Milutinov, Kuzma (second)
With two spots open for the two-way contracts.
I think you could build a contender around that group for sure, especially with a ring-chaser to fill in the shaky wing and center spots. Like maybe Splitter and Carter.
