I'm not basing any of my observations on stats, but from how they looked in the game. Regardless of how many points he scored, there's no way in a million years I would have come away from that game thinking that Rubio and LeBron have equal abilities because they had similar stats.
Regardless of Navarro's skills, he looked quicker than Rubio and influenced the gold medal game much more. I'm not saying we should go sign Navarro, but rather just pointing out that that Navarro had trouble in the NBA in part because he wasn't quick enough -- and yet looked quicker to me than Rubio.
Unless Rubio is getting quicker as he ages (which I suppose is possible, but not usually how it works), he's going to have problems in the NBA.
And let's also add that to be worthy of a lotto pick in NBA draft, esp. Top 5, you should be scoring double figures in the Euro league, I don't care how old you are. Rubio is scoring, what, 5 points a game, that doesn't cut it, even if he is a pass first player.
A lot of the fascination over this guy I think is because he has a cool name, has a cool style and look, which of course amounts to diddily squat when it comes to wins and losses.
In my mind, you put this guy through the pre-draft work out, assess his size and speed, performance in shooting drills, 2-on-2 games, etc. If this turns out all positive, and I trust Geoff's assessment, then we take the kid. Until then, he is a bust waiting to happen.
