Maybe others have brought this up. Maybe not.
The Clippers can now offer Gallinari, Gortat's expiring, Shai, and several first round picks for Davis and Hill. Shai would be better than any one piece the Lakers have to offer. The Miami pick could be really high. Frankly, the Philly pick could be high too depending on if they are able to resign Butler and Harris.
Then the Clippers can offer Leonard the max in the off-season. That would leave them with Leonard-Davis-Williams-Harrell-Hill-Robinson-Shamet, and possibly one of Beverly, Teodosic, or Muscala. Then, they could use a full MLE to sign another piece at guard and fill out their roster with minimums.
The Clippers have the most assets to offer for Davis right now. Depending on the Pelicans' priorities, their offer might even trump the Celtics, if they like Shai more than Tatum and they value cap relief.
