The NFL is the main reason I have an antenna... went HD when FOX was messing with its TW licensing, so I learned to make antennas, before the switch to ATSC for OTA broadcasts.
Which leads to my questions, what kind of antenna are you using outside? Any amps? What kind of feed lines?
How are the other Cobb's Hill stations? If all have issues, have you checked your feed lines?
Have you ever looked at your signal profile on TVFool
I'm 7 miles from the transmitters, but in Bushnell's Basin, with the creek in the back yard, it's a 2-edge diffraction signal, and signal strength like line-of-sight at 35 miles. See below for my antenna. Both 8 and 31 come in fine.

Outdoor antenna installations require special care, as they must be grounded properly, or a house fire from a lightening strike may not be covered by your insurance. Installation is a DIY project if you can stay indoors, like in an attic. You may need more antenna, but the benefits in peace of mind are substantial.
I built a clone of the ChannelMaster 4220 antenna
, a 4-bay bowtie design, with reflector, now marketed as the Ultratenna 60
. It's in the rafters of my garage, and I get all the major networks and a few of the "junk" channels. (I haven't looked at what comes in OTA lately...). This one's sibling is now hanging on my daughter's wall in Burlington VT, sans reflector, and giving her 18 channels (with subchannels).
Regardless, follow the TVFool link to see what your signal profile looks like, and decide from there.
Also be aware that there is such a thing as too much signal, resulting in "multipath" distortion (due to strong reflected signals, received out of phase) that can kill reception. Improved directional control, and rejection of off-axis signals, is one benefit of a reflector-based design, as is extension into the VHF frequency range (10 and 13 broadcast at VHF frequencies). The higher the gain, the better the directional control.
