I don't see the point of acquiring another 6'5-6'7 player.
We have Devin/Champ/Keldon/Barnes in the rotation and they're not going away.
No need to waste assets if it's not a legit PF. Whether by size or style of play, mostly on the boards.
Harper is too good already and hasn't broken the 30 minutes mark once. Just give him those extra minutes if needed.
That's already a 7 man rotation for 4 perimeter position, with Wemby/Kornet combo also being an option.
The only players I'd look at are PF/C hybrids to upgrade on Olynyk/Sochan or reclamation projects we can develop long term, like we did with Champ.
And there aren't any suitable PF/C targets, at least that I'm aware of, went through all the rosters a couple of times.
