I think the larger point being made here is, the players ARE capable of getting paid elsewhere, even if it may be less than they concievably could get in the NBA. Any money is more than the zero money they are getting paid during the lockout.
But the dispute isn't that they could find work elsewhere, it's that they're being paid too much.
And the best offer that a pretty good small forward (with upside!) could get was for 1/3rd of what he'd make in the NBA
Yeah, I think this helps dispell the argument that players are all going to go broke, and beg the owners for a job in November. However, I think that was overblown anyways. I think the majority of players saw this coming, and saved enough money to hold them over, and they will also find other ways to stay afloat during the lockout, whether it is playing overseas, or getting endorsements, etc.
What the owners are banking on though, is that the players still want to play in the NBA more than anything. They want the higher salaries, and the prestige that the NBA gives them over these other leagues. And, the owners aren't going to waiver on that until either a large number of quality players, or a small number of star players are willing to leave the NBA longterm, and are not going to come running back the second the lockout ends.
The owners know right now that they could show up at any time, give the players a little more of what they want, and the lockout would end, and every body (other than Chandler) would be in camp. As long as they have that in their back pocket, they maintain the upper hand.
