Somebody please tell me if this is crazy or not
Rozier is clearly going to sign an offer sheet with someone.
The Celtics could match it and then wait until December to include him in the trade for Davis. That would allow them to keep Smart since his contract wouldn't be needed for salary matching.
This idea works if New Orleans wants Rozier, which is one of the teams he's been rumored to fit on best, and New Orleans is willing to wait to make the trade.
I believe that Dec 15 is the date that free agents signed in the off-season are eligible to be traded.
The deal might be something like Tatum/Rozier/Yabu/MEM-pick for Davis. It's a pretty good deal for New Orleans if they're willing to wait a little longer. I don't see why they'd be in a hurry.
