To go off on a tangent, it is pretty unlikely that the Nets could pick up a PF that has an impact both offensively and defensively without parting with the Scowl (Brooksie). If the nets do decide to upgrade the PF spot through a trade, it's more likely that that player will have some skills, but also some warts. To step back a few miles, on the team the Nets have now--that is, with Devin, Vince, and Brook, is it better to have a PF that rates a 10 on offense and a 0 on defense; a PF that rates a 5 on offense and a 5 on defense, or a PF that rates a 0 on offense and a 10 on defense? Or some other combination? I think it's easy to criticize Boozer for his deficiencies, but the $1,000,000 question is whether the team can live with it, and flourish despite it.
Totally depends on other moves made. Boozer alone will not turn this team into a championship contender. It should be enough to get them in the playoffs, but at that stage why stop there. Perimeter defense would be the biggest need after Boozer. Other need would be a tough defender/rebounder at back-up center.
I guess no matter what they need a perimeter defender to make up for Harris and VC issues. So the question is does Boozer as a 10 on offense and 0 on defense benefit the team? I think so. The hope is that his presence would enable Harris and Carter to expend less energy scoring and have something left for defense. Najera as back-up PF comes in handy with Boozer. Yi is a waste to keep around at that point. Rather send him in trade and hang on to Anderson. Less issues with him if he doesn't get playing time.
