Barnes got a ton of minutes. He's just actually very limited and was also used ineffectively (but there aren't that many ways to use Barnes). Green is much better than Barnes in nearly everything but 3 point shooting-- and he's getting there.
And I agree that Kobe at 89 is ridiculous. You're really telling me he's going to step on the court day one and be as effective as Kevin Love, Tim Duncan, and Steph Curry? :P
I was really hoping with the new hires that rosters would be great out of the box. Looks like we're not quite there yet, and there's still a few misses with ratings based on hype or lack of it rather than what would be a more sober analysis.
