Irish Coffee: Does poor Celtics offensive rebounding matter?

Wake up with the Celtics [1] and your daily dose of Irish Coffee ‘€¦

Despite losing two straight games, if you look at the Celtics’ statistics, there’s not much they’re doing poorly over the course of this season. They’ve made more field goals than their opponents while taking fewer shots. They’ve dished out more assists, snatched more steals, swatted more blocks and committed fewer turnovers.

In fact, only one number sticks out. The Celtics have been out-rebounded overall by four. More specifically, they’ve been out-boarded on the offensive glass by 97 and rank last this year in the category that Red Auerbach [2] called “the hardest single phase of basketball.”

When you consider the fact that the C’s are shooting a league-leading 50.2 percent from the field — leaving fewer chances for themselves — that number is less glaring than at first glance, but does it matter at all? C’s head coach Doc Rivers [3] doesn’t think so.

“I’m not a big believer in offensive rebounds,” said Rivers. “I think if you if you get back every single time and not get offensive rebounds, you probably save more points in the long run. So, that’s not a concern.”

Anyone who watched Game 7 of the 2010 NBA Finals [4] — when the Lakers out-rebounded the Celtics 23-8 on the offensive end — might disagree with Rivers on that contention. While fans often rely on emotions for their arguments, Rivers can generally point to statistics to back up his statements, so let’s look to the numbers.

So, what in the hell does all this mean? Well, it’s safe to draw a number of conclusions from these statistics:

So, Rivers’ contention makes all the sense in the world when you look at the statistics, but the C’s coach also said “overall our rebounding numbers are Ok with us.” That’s a bit strange, since the defensive rebounding numbers don’t look too good, either. The Celtics hold their opponents to 43.9 percent shooting (5th-best in the NBA) but they also only grab 30.9 defensive rebounds (17th) while allowing 10.2 offensive rebounds per game (23rd).

Just as in Game 7 against the Lakers, Kendrick Perkins [7] can’t get back soon enough, because even the addition of the O’Neal “brothers” hasn’t helped shore up a concern for the Celtics entering this season.

NATE ROBINSON [8] RETIRES … FROM DUNK CONTEST

As we pointed out here [9] last week, Nate Robinson — the two-time defending champion — will not defend his NBA slam dunk title. Robinson has won three slam dunk titles in all (2006, ’09 & ’10).

Well, Robinson opened up to both NBA.com [10] and The Globe [11] about his absence from a slam dunk roster that includes Blake Griffin [12], Brandon Jennings [13], Serge Ibaka and JaVale McGee. Highlights:

CHARGES AGAINST MARQUIS DANIELS [14]‘ STEPFATHER DROPPED

I’m not sure if you’ve followed this story or not, but it’s a bizarre one. During Game 2 of the Eastern Conference finals against the Magic last season, Willie Buie — the stepfather of Celtics guard Marquis Daniels — was Tased and arrested for resisting arrest with violence.

On Tuesday, the charges were finally dropped [15], according to the Orlando Sun-Sentinel, based on the following facts:

Good thing those guys arrested him, huh? It only took seven months for the  courts to sort this one out. That’s got to be an all-time record. As Buie’s attorney, David Bigney, said: “The family is happy that this is behind them.”
