i dont think so. Maybe on the MU side, but not at all for OU. They will always have TX and OSU first. MU and NE were not true 'rivals' to all husker fans, but given the two years between OU games, MU was about the closest thing NE had to a 'rival' the last 7 years or so. games were back and forth and their seemed to be some dislike and importance put on that game from both players/coaches and the fans. It also helps that the north was decided by that game in 06,08,09 & 10. yeah MU has KU, and we hate KU, but Nebraska always felt like there was something important riding on that game.
I think most MU fans really want to beat OU, but its just not the same yet...we have yet to really upset the 'apple cart' by winning somewhat consistently against them. But who really knows at this point, things are just going to be wierd for me for a while with the new schedules.
