why would NO give up anderson for...anything? he makes 8 million per year, defends his position adequately (though not well), is maybe the best shooter in the entire league from distance, and rebounds well. he's like a young troy murphy, except maybe an even better shooter and cheaper.
unless you're offering a young star, i don't see NO giving him up. he's a building block role player--like a nick collison type, if that makes sense.
if the lakers want to move pau, they're going to have to take a downgrade in talent to compensate for his salary, or they'll have to take crazy salary back (i don't see the latter happening). the deals that the lakers are rumored to have shot down are probably more realistic: bargnani and calderon (stretch 4 and expiring contract), derrick williams, pekovic, and expirings (young player with unrealized potential and an excellent backup c). if the lakers don't want those, i believe they plan on keeping pau, at least through the season.
