steve nash, chris paul, kobe, deron williams, baron davis, ai
I will give you Nash, Kobe, and Paul. Even though Paul, and Nash aren't SGs they are playing better imo.
Point guards mean more to teams than shooting guards so it's hard to compare Williams, and Martin. I believe they are pretty much a wash in overall talent, but you take Williams off the Jazz, and they would suck again. Martin on the other hand wouldn't make as big of deal if out. That's why it's too hard to compare unless you look at straight talent vs. talent.
Now Iverson is getting a bit old. Talent wise I think it's a wash as well. Martin is getting better and AI is getting older. You can make an argument that if K-Mart got 19-20 shots a game he would be averaging 30.
Baron Davis is in the same boat as Williams. Cannot compare the two unless you go by talent. Talent wise they are about the same imo.
But the nod should go to Paul, Kobe, and Nash over K-Mart, but if he wasn't injured you definitely could make the argument that K-Mart is an all-star. Definitely.
EDIT: Roy, and Gay are having good years. Roy is a stud... Even though he is only averaging 19ppg I would put him in the same category as K-Mart because of talent level. Gay not yet.
