It's mindlessly easy to zero in on PP & KG as the 'problem' on the Nets, because of their high-profile arrival.
But really, that team currently has way more problems than those two.
Lopez has only played 8 games.
Williams has only played 9 games (and looked awful when was playing).
Kirilenko, expected to be a key defensive contributor and match-up sub for both Pierce and KG, has played just 53 total minutes.
Pierce was supposed to be playing just 24 mpg or so, but is averaging 29.8 due to the roster. His production was actually pretty decent to start the season (despite sub-par 3PT shooting) but I think the wear is starting to get to him as his points-per-36 has slipped to just under 16. Not bad, but definitely down a notch. He's still rebounding well at 6.3 rebound per 36 and an 18.4% DRB%. But, because of the poor shooting around him, his AST rates are down. I think, though, that once Pierce gets his 3PT stroke back, his overall numbers will start to look fine.
KG just looks totally 'off' with his jump shot. His overall stroke looks good, but he's flat on most of his shots. Without his jumper, his offense has clearly and obviously just dropped on the floor. And with Lopez out, he's forced to play C a lot more - which is actually when the team's defense has really tanked from bad to horrible.
With KG & Lopez both on the floor, the opponents have scored just 99.8 points per 100 possessions.
With KG on, & Lopez off the floor the opponents have scored 113.2 points per 100 possessions.
I think that may say more about the other guys playing PF next to KG in those situations.
The thing is, all these things, as bad as they seem, are all potentially just temporal.
Guys go through cold shooting streaks and then get it back. Williams & Lopez should eventually get healthy. And Williams has shown himself able to start the season playing crappy and then get his act together.
There is no guarantee the Nets WILL straighten out that ship. But I think it's still way too early to assume they won't.
