I believe Scott Van Pelt is on with Tirico today...I caught part of it on my way back from lunch.
One has to remember that while this is tragic, it is more localized event than a national one. While it would be nice for complete 24 hour coverage, it's not a necessity.
For those not local and are interested in keeping up, I highly recommend going to
Triple X ESPN Radio and
SportsTalk 980, as they are the 2 DC Area sports radio stations, and both offer live streams of their programming. I'd imagine both stations are doing something for Sean Taylor...
