it's about time, i watch/DVR NASCAR Race Hub via the FS2 encore airing as it airs live at 4 PM CT on FS1 against NBCSN's NASCAR America. i like to follow the latest NASCAR News and i like to watch both shows but both are on at the same time, i wished NBCSN would move NASCAR America to 5 PM CT or even 3 PM CT so it won't conflict with Race Hub on FS1.
back on topic, it's good to have it in HD now. now the only National Spots channel not in HD is ESPN Classic (but it mostly airs SD content and is only in Multisport packages and would most likely be phased out in the near future to turn ESPN 3 into an actual network instead of a Internet only stream service) and LHN (but that's considered an RSN then it would be a National Network due to covering just one college and that's UT.)
we have both Fox Sports networks, NBCSN, CBSSN, and the ESPN networks (ESPN, ESPN 2, ESPN U and ESPNews) in HD.
