If anything I think the question is. "Why have the Suns done this to the league?" Through a series of disastrous moves they have hurt the league in a variety of ways. Who is to say how bad of a precedent the Shawn Marion contract set for the league? You have a guy who is basically a great athlete with good BB skills making MVP caliber money. How many bad contracts were inflated by that bar being set? Those bad contracts hurt the whole league. Players become seen as overpaid chokers, and fewer teams have cap space to create compe ive teams. A lack of parity is never good, and bad contracts make parity harder to achieve.
And what about the Suns failure to get Steve Nash to the Finals? You know the league wants him there. They want a camera friendly, clean cut choir boy they can parade around for middle America to get behind. But instead of putting together a team and coaching staff that could win the big games they have settled for year after year of post season failure. Steve Nash hoisting a finals MVP to go with his other trophies would be great for the league. But the Suns can't get it done.
And let's not forget yet another black eye bestowed upon the league's image by Amare and Boris' deplorable actions. Just as the league was clearing the shadows of the Palace brawl they violate one of the most rigidly enforced rules in all of sports. Then, rather than using their media time to exalt the rightful winners and venerate the league's eventual champions, they slung the mud, and tainted the rest of the postseason. By the end of that series the entire world was against the Spurs. Turning the public against the team that would be shown the most was not good for the league.
So in answer to your question, no, the Suns can't save the league. In fact, I question whether they will ever be able to properly undo all the damage they've done. Come to think of it, maybe the league should contract their team before they dig the hole any deeper.
