If the NBA follows suit on it's marquee matchups for one of thei Christmas Day games, we should be seeing the Celtics and Lakers. From Slam Online:

Give up?

Actually, it shouldn’t be too hard to figure out who’ll be playing on one of the League’s marquee nights if you’ve been paying attention to the NBA (and its manic obsession with ratings) over the last few years.

Of course we’re getting the Celtics vs. Lakers on Dec. 25th. Who else could it possibly be?

From the Boston Herald (via Sports Media Watch):

The world-champion Boston Celtics will meet their NBA Finals rivals, the Los Angeles Lakers, at the Staples Center on Christmas Day. Ho, ho, ho.

The 2008 NBA Finals, though not necessarily the most compelling (certainly not after Game Four), were one of the highest rated in League history, so it makes perfect sense that the NBA would offer them up on their showcase night.

Makes perfect sense to me. You gotta figure that the NBA, along with ABC/ESPN, TNT, and everyone else, will be looking to take advantage of the popularity of this matchup, and what better time to do it than on Christmas Day?
