Not in relation to Jerami Grant (because I honestly don't think he fit the following description) but this is a very good point. I've said this before (not to you) but it bears repeating.
There is short term overpaid and long term overpaid and the Spurs should be fine with short term overpaid (for this season and next, IMO).
Devin (though performing well in his role) is long term overpaid and that might make him tough to move unless an opposing GM thinks he can still be unlocked in a bigger role. Barnes is an example of a guy who is probably overpaid, but it's short term (only two years left when we acquired him). Olynyk is another guy who is short term overpaid, but only 1 year left so no big deal. Porzingis is a guy we were allegedly interested in in the offseason, also overpaid... but expiring so again... no big deal.
I don't think Jerami Grant fits this because he has this season, next season and then a player option in the season after than (when Wemby's extension will be in effect). It wouldn't be terrible, but it's not ideal. Ideally we can find a guy who has one year left after this one.
Examples of vets who generally fit this criteria from Teams I'd target, contract wise (though maybe not on the court fit wise). I'm assuming all of these guys will exercise POs where they exist. Not all of these are overpays, but they are deals a team might want to get off of if rebuilding. I didn't look at rosters of contenders because they aren't looking to get off useful players unless getting a better player in return.
- DAL - Klay Thompson ($17MM this season and next)
- MEM - KCP ($21MM this season and next)
- MEM - Aldama ($18MM this season, $17MM next season, $17MM TO the season after that. You covered above why it might tough to get him though)
- MEM - Brandon Clarke ($12.5MM this season and next)
- SAC - Demar ($25MM this season and next)
- SAC - Monk ($19MM this season, $20MM next, $21.5MM PO after that)
- LAC - Nephew ($50MM this season and next). I'm not saying we should go after Nephew... but we probably would be find bringing in $50MM if it rolled off after next year. I'd have to run the numbers, but I recall this being okay when we were looking at Durant scenarios
- CHA - Bridges ($25MM this season, $23MM next). No way we ever tough this guy
- CHA - Grant Williams ($14MM next two seasons)
- CHA - Josh Green ($14MM next two seasons)
- CHI - Jalen Smith ($9MM next two seasons)
- IND - Jarace Walker (next season is the last year of his rookie deal). Just wonder if there is a scenario here where IND thinks they won't want to extend him and would rather just get off that $8.5MM next season to make room for a top 5 picks salary. Would they do Sochan + SRPs for Walker? This would get them off of Walker's money next year and give them some SRPs. They seem to like our SRPs (we've sent them SRPs the last two drafts).
- BKN - MPJ ($40MM this year and next). He's been discussed at length and I don't really like him and I don't think BKN is looking to get off this money. They honestly kind of need it to hit the salary floor and he becomes a very attractive expiring next year when they might actually want to do something.
- MIL - Kuzma ($22MM this year $20MM next). This would be a scenario where MIL completely falls apart but I actually want no part of this guy unless it's a sneaky way to get Ryan Rollins... who we were rumored to have an interest in but I'm don't think we have a place for. No one else on MIL fits the bill.
- GSW - Buddy Hield ($9MM this year, $9.6MM next year, PO for $10MM after that). What if Steph misses extended time and GSW completely craters? Draymond and Kuminga would also be on the block... don't really want any of these guys but Hield would be an interesting shooter at least... but not really.
- UTA - Kyle Anderson ($9.5MM this season and next)
- NOP - Jordan Poole ($32MM/$34MM). Yuck... no reason to take him on our team, even if they were including unprotected FRPs to take him. We're past this stage of our team where we need to do this.
- NOP - Not really this criteria at all... but would they move off Karlo Matkovic for an SRP? Would just be 3rd string C
Slim pickins out there as far as realistic trade targets who fit salary perfectly. There are guys with longer term, reasonable contracts, but I didn't spend a lot of time searching for them. But these are generally the rosters I'd look at. I don't know why anyone else would be selling right now.
