He just has to make it known that he wants out of Phoenix.
There's been a lot of speculation on whether or not Nash would ask for a trade, and while he's yet to do so, he needs to both for his sake and the sake of the Suns.
This could be the last chance for Nash to chase that ring. While he's made it known how much he likes playing in Phoenix, he's not going to get a chance at a championship anytime soon there.
It makes sense as far as the Suns organization as well.
Suns president of basketball operations Lon Babby has said all of the right things regarding the situation, and it wouldn't be a bad thing for them to keep Nash, who is still playing at a high level.
But championship-caliber organizations make bold moves, and while it may be unpopular to consider dealing the face of the franchise now, it could do more positive for the Suns down the road.
If they get a pair of assets and a first-round pick, then suddenly they have a good young core to build with along with Markieff Morris. You can add those parts much quicker by dealing Nash then you can by holding on to him.
This team needs to rebuild, and the ultimate goal should be a championship. It isn't going to win one with the current state of the franchise. It makes sense for the Suns to be aggressive in attempting to rebuild.
Phoenix has a great trade chip in Nash. It would be a shame to see it not take advantage of that.
As for Nash, it's not his personality to come out and demand a trade, but a ring is the only thing his NBA career is missing.
It may be the time for him to be aggressive in this situation as well.
