When David Beckham plays his first game for the Galaxy next month, I really do believe that the MLS will be the focal point of the entire sports media's attention for that entire week. Unlike the NHL, the MLS is shown on ABC/ESPN, and that Beckham game (the merits of his talent can be best debated in other threads) will be a ratings bonanza. Unfortunately for the NHL, ESPN is often what drives the major sports stories in America, and they will build up that moment like no other. All of their shows (Sportscenter, PTI, ATH, Cold Pizza, Between the Lines, etc...) will have Beckham/MLS related content. Given the fact that adidas is also a major contributor to the Beckham deal, and given their vast marketing machine, they will pump millions of dollars worth of resources into promoting his arrival as well.
Even though to many the MLS is considered a joke league, I really do think that it will become somewhat popular this summer because of that increased exposure to the casual fan. What could threathen the NHL ultimately is that the MLS has a tremendous buzz factor with the arrival of Beckham, while it seems that even one of the greatest teenage talents the NHL has ever seen has hardly created any buzz for the casual American sports fan. That's why as an NHL fan, I wouldn't be so quick to dismiss the MLS's status in America.
