I mean he gets to decide what's more important to him. I certainly think the NBA is a more prestigious prize.
I do think as the Olympics continue to get more competitive the relative value will shift for me.
Will they get more competitive, though?
What if we were rolling out Lebron, Curry, CP3, Leonard, AD, Westbrook, Harden, Wall, Aldridge, Blake, Drummond, Millsap, IT, etc? I mean, a team of NBA American players who aren't playing would handle our current team pretty handily. Some of these other countries have a couple of very good players, but there is no way in heck they would stand any chance against our 'best' line-up.
I do think if Spain, Australia, France, Argentina, or any other country actually beat the US for gold, it would be a superior victory for those NBA players than a championship, since it is a nearly impossible task.
