My predictions:
Bucks vs. Heat--Heat in 4. The Heat are too good for the Bucks, period.
Spurs vs. Lakers--Spurs in 5. I think the Lakers can get one, most likely at home, but the Spurs are winning for sure.
Nuggets vs. Warriors--Warriors in 6. Definitely one of the more difficult series to evaluate, and I think it'll be pretty close. The Nuggets were very surprising in the regular season, especially after losing Gallinari. But while they boast a better regular season record, they don't really have any superstars to step up in the clutch. Sure, Andre Miller made that game-winner, but he's typically not that kind of player. The Warriors have a budding superstar in Curry to rely on. It's going to be a close series regardless.
Nets vs. Bulls--Chicago in 6 or 7. Deron Williams finally found his stride after the All-Star Break, but he was contained in that second game. The Nets have more offensive talent, but the Bulls function better as a defensive unit. I think the Bulls' defense will end up trumping the Nets' offense, but this will be an interesting series to keep an eye on.
Pacers vs. Hawks--Pacers in 5. I don't know much about either team, but the Pacers look like the superior group on paper. They backed it up with a pair of convincing wins as well. The gap between their regular season records isn't massive, so I wouldn't be surprised if the Hawks take one.
Thunder vs. Rockets--Thunder in 5. I agree that the Rockets will give the Thunder a scare, but I doubt this series will go past 5 games. The only player they can rely on consistently is Harden. Lin and Parsons can have big games, but they don't come as often. Delfino seems to strictly be a three point shooter with limited offensive skills. The Thunder have Westbrook, Durant, and even Ibaka to go to for points, and Kevin Martin, while streaky, is a lethal scorer. If the Rockets can get good games out of Lin and Parsons, they might be able to steal one. Otherwise, the Thunder are almost guaranteed to win.
Clippers vs. Grizzlies--Clippers in 6. The Grizzlies will put up a tough fight, but the Clippers have Chris Paul. Even though he's slowed down, I've seen it too many times: when he wants it, he's **** near unstoppable.
Knicks vs. Celtics--Knicks in 4. Without Rondo, the Celtics are just a bunch of outdated (super)stars with some younger, inexperienced roleplayers. Jeff Green has stepped up, but the Knicks are simply too much for the Celtics to handle.
