I doubt OKC is even interested in Lauri at this point. They got their 3 stars. They dont need or probably even want another max level player (at least one they have to give up significant assets for). They will be making moves on the margins to compete w/ whatever the meta shapes up to be.
That's what I've been saying for awhile. They just need a guy that can give them some minutes against the 250+ pounders and grab some rebounds.
That said, I'm sure they would love Lauri, and I think they still have a couple years before they need to pay guys, so they could probably afford to pay him for awhile and flip him if needed down the road.
