Rapid Reaction: Heat 88, Bulls 65

CHICAGO -- Let's take a quick look at how the Miami Heat cruised to an 88-65 win over the Chicago Bulls on Monday night at the United Center in Game 4 of the Eastern Conference semifinals. The Heat lead the series 3-1.

How it happened: LeBron James had 27 points, seven rebounds and eight assists as the Heat had their way with the Bulls throughout the night. Chris Bosh added 14 points and six rebounds as Miami took a commanding lead in this series. Carlos Boozer led the Bulls with 14 points and 12 rebounds, but he was just 3-for-14 from the field.

What it means: The Bulls appear to have hit the wall. Specifically, Nate Robinson seems to have finally run out of gas. The diminutive guard has been integral to the Bulls' success in the postseason, but he had his worst game of the season on Monday night going 0-for-12 from the field. As a group, the Bulls couldn't find any kind of offensive rhythm, but it was Robinson who struggled the most. It seems as though all the minutes and all the nagging injuries have finally caught up to him. So often over the past few weeks he has been able to find an extra gear in his game and will his teammates to the finish line, but he couldn't buy a basket in this one. Without his offense the Bulls couldn't get anything going. It's not just Robinson's fault that the Bulls lost because the rest of his teammates weren't shooting well either, but Robinson's lack of production was most jarring given the standard he has set for himself during the playoffs. This game only underscores what has been the Bulls' biggest problem for the past few seasons. When Derrick Rose isn't on the floor, they have nowhere else to turn against Miami. Against weaker opponents, the Bulls can usually find ways to score and win because the defense isn't as strong. Against Miami, it's a different story. Until the Bulls find a consistent option next to Rose they will be unable to take the next step in their development as a championship contender.

Hits: Udonis Haslem gave the Heat a solid performance, scoring six points and grabbing seven rebounds in 18 minutes.

Misses: The Bulls shot just 25.7 percent from the field and turned the ball over 17 times.

Stat of the night: The Bulls' 25.7 shooting percentage is a new franchise low for postseason play. The old record was 31.1 percent, set in the 1990 playoffs against the Detroit Pistons, according to Bulls radio statistician Jeff Mangurten.

What's next: Game 5 is Wednesday night in Miami at 6 p.m. CT.
