That Nets team is going to fuck shit up as long as it's healthy. It's got too much talent, and is theoretically too deep. Even a rookie coach can't blow this. As much as he's a rookie coach, he's also Jason Fucking Kidd. He played with or against every single one of these guys, and aside from being a drunk wife-beater I don't think he's got any beef with the players on his team. In fact, given that he's Jason Fucking Kidd, I'd wager they respect him greatly.
You figure chemistry might be an issue. You figure age/injury might be an issue. But aside from that, the team is balanced offensively both in starters and bench guys, and should defend well too. Deron's unhappiness can't even ruin things, because no matter how much of a diva or star he wants to be, he isn't yet more relevant even today than his coach, or KG/Pierce. KG alone will likely shut that shit down if it threatens the ability of that team to win.
In conclusion, why can't Dolan make some back-channel illegal money laundering type FA deals? Goddamn.
[EDIT: Nobody of relevance on the Heat roster took a paycut. They all got max deals with no tax. You think Bosh would net more money *not* on the Heat? Or Wade? Or LBJ? Stop.]
