If George doesn't want to sign with the Lakers, then he'll just leave in the offseason anyway, and they'll have lost Ingram for nothing.
Also, as bad as Deng's contract is, they can probably find a way to lessen it's impact. I don't understand the cap nuances enough to evaluate this, but one thought on how they could reduce it to essentially 3m/year long term (spreading it out, but making a path to have room for 2 maxes this summer): http://bleacherreport.com/articles/2743657-to-make-room-for-2-stars-lakers-should-give-luol-deng-an-extension-seriously
