The second team will be better defensively, especially on the interior. I also think team 2 will have better three-point shooting and floor spacing on offense.
You think Bass / Humphries / Sullinger / Olynyk are going to defend the rim? Like, at all?
Where's this floor spacing you're talking about?
Bradley is a streaky shooter at best; Green is an okay outside shooter, but not really any better than Deng. Wallace can't shoot to save his life. Lee is a solid spot-up shooter. Pressey maybe can shoot, maybe not. Olynyk is probably a good shooter, but I'd expect him to be inconsistent as a rookie. No better than Villanueva as a shooter. Bass's range extends to 15 feet.
In terms of defense, JJ Hickson is the big man equivalent of MarShon Brooks or Jordan Crawford, with a reputation of not caring about defense. His matador defense is why he has moved around quite a bit. Charlie Villanueva also has a poor reputation.
Meanwhile, I think there is a decent chance that, despite their flaws, the Celtics big man corps will give more effort on defense, so that their interior defense will be better than that of your hypothetical team.
In the 2012-2013 regular season, Green shot 38.5% on long twos, compared to 35.3% for Luol Deng, and 38.5% vs 32.2% on threes. Green seems to stand a reasonable chance of maintaining or improving upon his shooting numbers, since he was getting better as the season progressed, while Deng seems to be declining and I doubt he will get better at this point. It would be wrong to say that Green is not really any better than Deng. Brandon Bass took 35% of his regular season shots from 16 feet or longer and he made 45.2% of those. 15% of his shots came from 18 feet or further and he made 43.3% of those. To say his range extend to 15 feet has no basis in fact.
It would take too long to go name by name, but you seem to be treating superficial similarities as if they are concrete equivalencies, when that comparison is not backed up by numbers.
