I can't imagine a more unattractive product than listening to Justin Maxwell, while watching a 70 win team. Please don't let that happen. Morse would be even worse.
I mean, is Washington, DC a major media/sports market, or not? Judging by the overall quality of "sports radio" (to include team announcers/commentators) in the area, my answer would be "no." Even Bmore (a decidedly lesser media market) has had top guys like Jon Miller, Gary Thorne, etc).
