The lakers have like 6 power forwards as it is, losing a SG and gaining another PF just seems excessive, and the lakers know matching up salaries with Amare and Kobe would be near impossible when they can easily calculate a marion trade.
While they have every right to be, wanting Amare would be selfish, and not very constructive to either team.
To be completely honest I think KG/Amare/Nash would be 10 times more exciting than Kobe/Amare/Nash
Kobe is too good -- along with an amazing passer and a big man that can finish I just think we would be desensitized as the highlight reel would be abundant, but it wouldnt be quality team work, it would just be amazing basketball. With KG the entertainment factor would be much more tangible, as I think the team would be amazing, as opposed to a bunch of superstars who are all good.
And in regards to the longevity of the team when comparing kobe/kg, I dont think that is as high as we think on the suns priority list.
Like a 40 year old virgin; winning the prize just once is more important than trying to find someone who can do it 3-4 times for you.
