Wake up with the Celtics  and your daily dose of Irish Coffee ‘¦
I’ve got to hand it to colleague Jerry Spar for this one. It’s not surprising that the Celtics haven’t performed well on back-to-back nights when the second game is on the road, regardless of where the first game is played. What’s surprising is how putrid they’ve been in those situations this season.
And they’ve found themselves in that situation again Friday night, as the Celtics take on the Suns in Phoenix less than 24 hours and 1,300 miles removed from defeating the Trail Blazers 88-78 in Portland Thursday night.
Here’s how the Celtics have fared on the road during the second leg of back-to-back nights:
- Oct. 27 at Cleveland: 95-87 loss
- Nov. 8 at Dallas: 89-87 loss
- Dec. 9 at Philadelphia: 102-101 win
- Dec. 29 at Detroit: 104-92 loss
- Jan. 8 at Chicago: 90-79 loss
- Jan. 22 at Washington: 85-83 loss
Note: This doesn’t include the Nov. 22 game at Atlanta (a 99-76 win), because the game the day before (at Toronto) was played in the afternoon, not at night — allowing for extra travel/recovery time.
For those of you counting at home, that’s a 1-5 record in such instances, with the lone win a one-point decision over a 20-25 Sixers team that required a Kevin Garnett  alley-oop with 1.4 seconds left.
The Celtics have five remaining games in these situations:
- Friday at Phoenix
- March 14 at New Jersey
- March 19 at New Orleans
- March 28 at Indiana
- April 1 at Atlanta
Note: This doesn’t include Feb. 7 at Charlotte or April 11 at Washington because the games the previous days are in the afternoon.
Spar took this breakdown further, noting that the C’s have had four occurrences when they’ve played the second game on back-to-back nights at home (the first game was on the road each time). They’re 4-0 in those instances.
The fact that the Celtics are four-point favorites tonight in Phoenix makes all this even more interesting.
THE CASE FOR KENDRICK PERKINS 
I won’t bore you with in-depth statistical analysis like I did the other day, so I’ll let the New York Times do it for me. If you like this stuff, as I do, you’ll love this piece  about why Kendrick Perkins makes a huge difference.
While Perkins’ 36-minute averages last season of 13.2 points and 9.8 rebounds are good, they don’t reflect the Celtics center’s impact, particularly defensively. Even the adjusted plus/minus statistics that author Michael Lewis  unveiled to portray the relative value of a player like Shane Battier  don’t help Perkins’ case.
Over his last two seasons of action, Perkins has posted a -5.76 adjusted plus/minus , one of the worst marks in the league. Adjusted plus/minus is far from infallible, but characteristically it favors guys who fall in line with Perkins’ reputation: tough-defending, solid-rebounding, low-usage role players on winning teams.
Furthermore, when you look at the production of his individual opponents, Perkins’ 2009-10 numbers aren’t so favorable, either, as they were for Battier.
In each of his last  two  seasons, Perkins has allowed opposing centers to produce at an above average rate, a curiosity for a well-regarded player whose primary contributions come on the defensive end.
Yet, when you examine his per-possession statistics, it sheds some light on Perkins’ value.
According to Synergy Sports Technology , Perkins allowed just 0.77 points per possession in the post during the 2009-10 season, a truly impressive mark. Opponents on the low block shot just 38.5 percent despite their proximity to the basket, and Perkins, amazingly, fouled opponents on only 6.3 percent of their post-up possessions. Go back to the 2008-09 season and the numbers get even better: 0.73 points per possession allowed and 35.4 percent shooting.
Following an ugly, ugly game that saw the Celtics tie a season-high for turnovers (21), the Trail Blazers still had high praise for their Eastern Conference foes. Here ‘s what they told the Oregonian:
LaMarcus Aldridge: “They showed why they are champions. They played championship basketball. They do a good job of taking away the paint. Every time I wanted to go middle, I never saw anything [open]. I tried to force it a couple times, turned it over, but I think they are one of the best teams at not … letting you get to the basket.”
Nate McMillan: “That’s a great team. That team is prepared and built to win a championship. I thought our guys scrapped. I thought they played hard. They battled tonight. But they have so many options that they can go to. When you have that many options and that team is locked in to playing that way, knowing how to win. It’s going to be a tough game.”
Two other interesting statistics from the Celtics’ victory on Thursday night:
- Portland out-shot the C’s, 90-64, but made only three more field goals (33-30).
- In just 31 minutes, Kevin Garnett nearly recorded his first triple-double of the season (10 points, 9 rebounds and a season-high 9 assists).
