This is one the primary reasons I have not watched anything sports related on NBC for a long time. The rah-rah, the overly obsessive coverage of only US players and related history, the focus on all the wrong parts of the games, I can (with great effort) tolerate. But once you add the absolutely useless and inane commentary and the tendency to shove the schedule on me, I prefer to switch to other sources and I strongly recommend that to as many people as I can (while trying not to be a grouch).
This was done to such a degree during the last FIFA world cup that I chose to watch it in Univision even though the only two words I understood were pelota and goal. And even that was oodles better than NBC. I wish I could stream CBC from somewhere or at least pay for coverage that just keeps the damn commentators quite unless absolutely necessary. Unfortunately AFAIK the way the whole thing is setup, there really is no choice in the matter.
