It is reported that the Lakers are desperate to move Pau Gasol and the Celtics mentioned as a possible destination due to our available cap space and if KG decides to retire:

On the downside, Gasol turns 32 this July and is coming off his worst playoff performance. He is also owed $38.3M over the next two seasons.

Gasol has very good offensive skills, and the Celtics brand of ball could make him a tougher player on defense.
