The way things are looking now, it doesn't look like we're getting JO, since if the Pacers finally bend over and stop demanding a riduculous price for O'Neal the Lakers will be their first option and will jump on that oppurunity. Don't get me wrong, I hope we get him, but it looks like our chances are slim.
I think bringing a decent big man and a three point shooter would be good moves. The big man would be a defensive specialist to help guard Garnett, Bosh, Randolph, Howard, etc. He needs to be good rebounder as well. What some of you are forgeting is that bringing Jermaine O'Neal to the Nets wouldn't solve the problem of guarding other star big men. Sure, he's a good post defender, but what makes him and other big men like him stars is that they are offensive weapons and can't be stopped that easily. Jermaine O'Neal wouldn't do a better job on Kevin Garnett than a lesser big man who plays great defense. O'Neal would help us a lot offensively and would be able to slow down some other team's big men, but it's not like he's Bruce Bowen. He won't be able to shut them down. Look at Kobe Bryant for example. He's considered a good defender, but if he faces Tracy McGrady or LeBron, he won't hold them to 15 points. On the other hand, Bruce Bowen (A DEFENSIVE SPECIALIST) can. See my point?
Jermaine O'Neal would be HUGE for the Nets and will put us in the leageu's elite offensively. But he's not good enough defensively to shut down any big man in the East. That's why we need a defensive specialist, whose sole job is to do that and grab rebounds. I don't see the point in bringing two decent big man, when we already have 5 on the roster. One is enough.
