Responding to the OP, I've said before that I think 20-30 years from now, Nash's career will shine more brightly than Kidd's career. While you say the top 5 PGs are Magic, Isiah, Cousy, Stockton and Kidd, I'd absolutely swap out Kidd for Nash.
Not only did he win the MVP twice, but those two years the Suns were considered by many to be one of the favorites, if not the favorite, to win the championship. It's not unreasonable to say that they would have done it too if not for a couple of high profile screw jobs in the playoffs.
Kidd made it to the Finals, but that was more a function of being in the weak East than anything.
As with others, I say Nash gets in - no problem. And he'll absolutely deserve it.
