the Suns were always trying to go with 2 PGs at a time for a while. After KJ retired, they went out and got Penny Hardaway and played him in the same backcourt as Kidd but thats when he started getting hurt all the time.
Nash, in his first go-around with the Suns, didn't do anything. He was a basically an end-of-the-bench guy until he developed out of nowhere in 2001. Took him 5 years (after being a 4 year college player) to do a thing in the league. Then he became a Hall of Famer all of a sudden.
