A pair of 3-pointers, a fast break dunk off a steal and a driving layup by LeBron James  in the final 2:10 capped a 16-0 run that gave the Heat a 97-87 victory Wednesday night and ended the Celtics  season after five games in the Eastern Conference semifinals.
Nenad Krstic  scored the C’s final points of the season, with 4:28 remaining, giving the Celtics an 87-81 lead. But James broke an 87-87 tie with 2:10 remaining, and then buried a go-ahead trey with 40 seconds left after Jeff Green  mishandled a poor Paul Pierce  pass. After a timeout, Delonte West  turned the ball over and James put the game — and the C’s season — away with a dunk and a layup seconds later.
WHAT WENT WRONG
Paul Pierce’s early foul trouble: With the Celtics leading by three and James cruising for a breakaway dunk, Pierce committed a truly ill-advised foul just 5:40 into the game. Not only that, but it was Pierce’s second personal, forcing coach Doc Rivers  to give him an early hook before bringing him back for the second quarter. Pierce then picked up his third foul late in the second quarter and missed the final 1:44 of the half. He never got into a rhythm and couldn’t provide any physicality on the defensive end.
Dwyane Wade’s monster first half: While the rest of his teammates made just 6-of-24 first-half shots (25 percent), Wade buried 9-of-12 from the field and 5-of-9 from the free-throw line for 23 points before the break. While the Celtics shot 52.9 percent for the opening 24 minutes, the Heat trailed by only two points (49-47) at the half — thanks to Wade and the Heat’s 23-14 advantage in free-throw attempts. Wade had 15 foul shots in all, and overall, the Heat totaled free throws 38 to the Celtics’ 20.
Rondo’s health: At one point in the fourth quarter, both Rondo and Jermaine O’Neal  were receiving back treatment on the sidelines. And how could you forget Rondo was already dealing with a dislocated left elbow that left him at 50-50 prior to the game? He did not play in the fourth quarter, finishing with six points and three assists, despite a valiant effort. O’Neal also missed the final quarter, totaling just three points and two boards.
Careless turnovers: Garnett and Pierce combined for seven turnovers, and the Celtics committed 17 in all — the majority of them seemingly unforced. Down 3-1 and on the road, the C’s couldn’t afford to give the Heat that many extra opportunities.
WHAT WENT RIGHT
Getting KG involved early: The Heat crowd may have arrived late, as usual, but Garnett showed up right from the opening tip. He attacked the paint and scored nine of the Celtics’ first 13 points, finishing the first quarter with 12 points, five rebounds and two steals to help the C’s grab a 24-16 before the Heat and their fans even knew what hit them. Considering Garnett’s Game 3 success (28 points, 18 rebounds) and Game 4 failure (7 points on 1-of-10 shooting), the Celtics needed Garnett to set the tone. Unfortunately, he scored three points the rest of the way.
Ray Allen gets open looks: After struggling to find space and making only 11-of-30 shots in Games 2-4, Allen got free from Wade and made 6-of-12 from the field in Game 5, including 5-of-10 shooting on some pretty wide open looks from beyond the arc (not to mention a huge four-point play). His 11 first-half points helped pick up some of the slack left by Pierce’s relative absence.
Nenad Krstic and the bench (yup, you read that right): At the end of the third quarter, Krstic buried a long baseline jumper that put the Celtics up 73-71 heading into the final 12 minutes of play. Krstic finished with eight points as the Celtics’ bench outscored the Heat’s 33-12. Krstic, Jeff Green (9 points), Delonte West (10 points) and even Glen Davis  (6 points) each scored at least six points on the night.
