Just my guess, but remember that annoying anchor for AC34? Todd Harris? Well, the $$golden child$$ for NBC Sports is the Tour de France, which Todd Harris is the anchor, along with Bob Roll and Christian Vande Velde. Unfortunately, the Tour de France is happening right now and at the same time as Portsmouth. To broadcast live, both are happening simultaneously. NBC Sports is just one network. They are not going to bump the Tour to broadcast ACWS Portsmouth. Ain't gonna happen.
They have 2 channels on Direct TV so we will see. I doubt NBCS will actually film the events. They would just pick up the feed and broadcast.
