How is that fishy? For a guy who doesn't make use of his athleticism much, it is plausible that he actually got better with age. His shooting percentages are through the roof, the best of any PG in the league in fact, and this is at age 35. No matter what the system, you have to be very good to be able to score at a clip like that. Additionally, I think that Nash struggles on the defensive end are overblown. It's not that he isn't bad on defense, it's that the rest of his peers aren't that great, either. Who in the league, aside from Rondo, is a 'good' defender at the PG position? Chris Paul gambles, much like Iverson used to do, and gets a ton of steals, but I hesitate to call him a good defensive player because of that. It's like saying Larry Hughes plays good defense.
What a hater. Nash hasnot become any stronger or anything. He has simply taken control in Phoenix and has basically become the system. He's not really athletic and I doubt he can dunk now, but his shooting touch is still amazing.
