To see non conference games, the SDQL text is:
not C
If you go to the query page at Killersports.com/nfl/query
and type it into the query text box and click on the query button, you can see all the games.
If like, you can break them down further by home team, but OU line, by W/L records, line etc.
If you scroll down, you can see the upcoming games as well.
To see only this season, use:
not C and season=2013
I get 40-13-1 OU for this season's non-conference games.
