NBA Playoffs: Are the Chicago Bulls Done?

The Chicago Bulls shocked the world by stealing Game 1 of the second-round series against the Miami Heat, but they have yet to win a game since then.

They went 0-3 in their next three games, and they really haven't put up a good performance other than in Game 3, which they lost at the end anyway.

In Game 2 and Game 4, the Bulls shot just 36 and 26 percent from the field, respectively (per Basketball Reference), and those concluded in two blowout losses for the team struggling to find any sort of offensive flow.

Injuries Taking their Toll

Besides the obvious Derrick Rose injury, injuries to key contributors like Luol Deng and Kirk Hinrich have dealt the team a heavy blow in this series.

Neither of them have seen any action against the Heat, and their contributions have been sorely missed throughout the series.

Deng was their best option to defend LeBron James, and he took the challenge of guarding James every time the Bulls played against the Heat during the regular season. He is their best and most versatile individual defender, and he held opposing small forwards to a PER of just 11.2 during the season (per 82games.com).

Hinrich doesn't have as large of a role as Deng, but he provides steady point guard play and played excellent perimeter defense on Deron Williams during the series against the Brooklyn Nets. During the regular season, he held opposing shooting guards to a PER of 8.8.

Although Jimmy Butler and Marco Belinelli have stepped up in their absence, they have clearly showed fatigue when guarding two of the best players in the world in James and Dwyane Wade, while trying to produce on offense as well.

Furthermore, it's highly doubtful that either Deng or Hinrich will be back for Game 5.

Nate Robinson and Carlos Boozer's Struggles

Robinson was the hero in the Nets series and Game 1 against the Heat, but he has clearly slowed down after that.

Boozer seems to be back to his inconsistent ways, as he went just 3-for-9 in Game 2 and 3-for-14 in Game 4. Robinson, on the other hand, went a putrid 0-for-12 from the field in Game 4 and finished the game with a big zero on the scoring column.

Unfortunately, Robinson and Boozer are the team's two best scorers and the two most important players on this team. If they don't produce on offense, the rest of the team struggles on offense.

Although Joakim Noah has been relatively consistent, he cannot lead this team to victory by himself.

Robinson will have to find some kind of spark or motivation to get over the hump, and Boozer is having flashbacks of his poor playoff performances in the past few years.

The team's chances of getting back into this series starts and ends with how well Robinson and Boozer play on the offensive end.

Defense alone cannot make the Bulls win this series and that was clearly evident in Game 4. They held the Heat to 88 points, but they held themselves to just 65. They must have their best offensive weapons contribute, or else every game for the rest of the series will result in a similar score.
