In what comes as little surprise Grant Wahl reports that NBC Sports is pursuing Arlo White as their primary play-by-play man for their first season covering MLS and the United States national team. NBC isn't stupid and, like Sounders fans, feels that Arlo is one of the best voices in soccer right now. There is no indication that this is more than interest from NBC towards the Seattle Sounders voice.
It is notable that JP Dellacamera pulls double duty as both a national voice with FoxSoccer and the local voice of the Philadelphia Union. That duty is bit easier when in the northeast with the greater density of both MLS and USMNT games, but does show that splitting duty can be done.
Dellacamera's color man on Union broadcasts is Taylor Twellman. Twellman has also pulled double duty showing up in studio as analyst (and even host) as well as a color man on various ESPN broadcasts. He now looks likely to replace John Harkes.
There will be change more change over the next few years when it comes to the play-by-play, color and studio work with American soccer as NBC launches from the ground up and with Fox ramping up for 2015 when it takes over the FIFA contract. It would be a shame that a team that gets as much local attention as Seattle loses its primary voice, even if is as a stepping stone to greater things for the individual. Losing White entirely would mean that the national media gains a very blog friendly voice, as Arlo made it clear at Date with Sounder at Heart that he enjoys reading the medium and finds it a uniquely American aspect to sport.
