This is very tough for me to say being a Celtics fan but due to the over the top tanking tactics of the 76ers over the last several years I'd rather see him in L.A. than Philly. For your Lakers I think it'll come down to what their first priority is. If they can't pull off a trade for Cousins where do you think they should start, the back court or the front court? Both Russell & Okafor were excellent in college. Oh yeah...has Randle fully recovered yet?
Personally, I prefer Russell, but not by enough that I would be upset if they got Okafor. There are also bigs like Love and Aldridge who are rumored to want to be in LA and they are unrestricted, so it may be easier to get a big through FA than a guard of SF.
