If you can do White, TL, and say Gallinari, then you do it and don't look back. I wouldn't do 3 1sts, but would probably do 2. I try to hold on to Grant if possible.
Obviously TL and White are big parts of our team, but AD would obviously fill TL's role and Pritchard would just need to step up and play more minutes. You'd also have a couple of empty roster spots to look for another Guard.
I realize the Lakers probably want more, but that is a decent haul for them. They aren't exactly going to win the Wemby sweepstakes so it is best for them to rebuild on the fly with proven young players on long contracts. And they even get a couple of picks out of it.
