Please remember that Pau existed at a time IN THE WEST, with 3 of the best PFs of ALL TIME prior to reaching his prime on top of other forwards/bigs like Bron, Melo, Bosh, TMac, and Dwight being in the league. His teams in Memphis were also just DECENT. That is the perfect storm of reasons why he wouldn't be making All-Star teams and All-NBA teams prior to being in LA.
Odom was also naturally in his prime years with the Lakers. Ages 25-31.
I'm not saying Kobe didn't help them, but it's pretty obvious that good players are going to play well when they are in their primes.
