Yes you are wrong. UND got some games back on fcs this year, but not all as they did prior to the league's cbssn contact. Although dish doesn't have a specific fcs channel, all the games that have been on fcs are on dish alternate sports channels, as you no doubt found.
The only way to see all home games are cable tv, either midco cable or another cable company that pays midco for the station (or pay for the nchc.tv stream)
