Have to agree here. Nash can give Amare easier buckets. Amare is averaging 21.1 PPG (career) and Nash is averaging 8 APG (Career).
You should only consider Nash last four years - or the three when Amare was healthy, when he averaged over 11 assists a season. Interesting fact, he had the least number of dimes in 05-06, the year Amare went down, unfortunatelly there is no such statistics, but anybody who watched the games can tell that over 50% of Nash's assists were to Amare and there is no assist for FT's but its clear that Amare went to the line a lot because of that almost perfect pick n roll with Nash.
I wont say that Nash made Amare dominant, but as nowagimp stated Steve helped STAT an awful lot when he was a one dimensional player. I have to add that to be a real dominant force Amare still has to be a better post up player, but its good to see signs of development in that area of his game too.
