Perhaps it’s appropriate that so many movies and TV shows got established near Los Angeles. For, almost 30 years after Showtime, it’s apt to ask whether the Lakers-Celtics rivalry has jumped the shark.The league, one could argue, has moved on to newer, hotter teams, such as the Miami Heat of LeBron James, Dwyane Wade and Chris Bosh in the Eastern Conference ? and in the West, the Lakers’ fellow La-La team, the Clippers, with the man who dunked over a Kia, Blake Griffin.The Lakers and Celtics, meanwhile, are each only a few games above .500.Well ? let Blake dunk a few more alley-oops and let LeBron power his way inside. Lakers-Celtics is still where it’s at.Like one of those 1970s disco balls, this rivalry has been spinning ever since the Lakers left Minneapolis for Los Angeles, lighting up the NBA.The rivalry keeps shining because the owners of both teams want them to dazzle. Lakers majority owner Dr. Jerry Buss and Celtics CEO, governor (the titles these guys come up with!) and co-owner Wycliffe “Wyc” Grousbeck have teams built to contend for Banner 17 out West ? and Banner 18 in the East.In fact, the Celtics-Lakers rivalry has gotten, to borrow a phrase from country star Sara Evans, “just a little bit stronger.”We cannot forget how bad the Celtics played as recently as the 1990s – and we certainly can’t forget the tragic deaths of Len Bias in the late 1980s and Reggie Lewis in the early 1990s.While the Lakers stayed competitive even after the end of the Magic-Bird showdowns, bringing on Kobe Bryant and Shaquille O’Neal, Boston lost its edge.In recent years, the Celtics-Lakers rivalry has flourished again. It was only four short years ago that we saw Boston do what it has traditionally done – beat the Lakers in the Finals – with the new Big Three of Ray Allen, Kevin Garnett and Paul Pierce. It was just two years ago that we got another exciting Finals, even if the result didn’t go our way.Maybe next season, the Celtics implode worse than the U.S. economy did in 2008. Maybe Kobe can’t keep the Lakers afloat next year either. At least for now, though, the C’s and Lakers can quote Gloria Gaynor’s motto, “I Will Survive,” and keep the disco ball shining and spinning for the rest of 2012.Rich Tenorio can be reached at [email protected].
