i disagree, i think the spurs have better talent.
parker vs nash, i would take parker. nash is great at 3's but the 3 point shot is a streaky shot that cannot be depended on. parker on the other hand isnt a very good 3 pt shooter but he scores 25pts a game with lightning quick dribble penetration for easy layups. all game long, you see parker speeding down the court attacking the rim for a layup or a foul and a trip to the free throw line. i'd also take parker's D over nash's.
sg's - not even a contest. manu all the way.
sf's - bruce bowen can guard 1-3 maybe even the 4 also sometimes. he is a capable 3 point shooter. on the other hand, i think this one could be a tossup between either team. I personally would take bruce bowen though.
pf's - you could say that tim duncan and amare cancel each other out, but tim's defense > amare's defense by a mile. i would take tim over amare. im sure you would too. tim is the greatest pf ever.
c - shaq vs oberto? shaq, but its not like he's a difference maker anymore.
so the spurs are more talented and are much more experienced champions. on top of that, they can actually play great defense.
