Outside of the Nuggets, I think Gallinari would fit best in this situation.
The main piece the Clippers still need is a small forward. A starting lineup of Baron Davis, Eric Gordon, Danilo Gallinari, Blake Griffin and DeAndre Jordan could be in the playoffs as early as next year.
They've reportedly already offered a first-round pick in exchange for Gallinari, but some think Denver may want more.
They could combine a pick with the expiring contract of either Rasual Butler or Craig Smith. That may be enough to get the deal done.
If they really want to entice the Nuggets, they can offer to take on the contract of Al Harrington (another player Denver wants to ship out as part of their rebuilding).
Los Angeles could give Denver three expiring contracts (Butler, Smith and Brian Cook) and a first-round pick in exchange for Gallinari and Al Harrington.
Harrington isn't a great pickup for the Clips, but he's not horrible either. He could be a solid asset off the bench, as he could offer relief to the starters at three positions (small forward, power forward and even center).
The addition of Gallinari to this team would be huge. It would give them another young player with a lot of potential to grow up with Blake Griffin, Eric Gordon and DeAndre Jordan.
Gallo and Gordon would stretch the floor with their shooting and create space for Blake Griffin to operate inside. Plus, DeAndre Jordan has the potential to develop into a great defensive player and could be the team's leader on that end of the floor.
Then you have Baron Davis their as the mentor (he'll be motivated by all the youth around him).
With all that in place, the Lakers could have reason to worry about their Tinsel Town dominance.
