Basing that off one game? Robinson had a terrible game last night, but to say he's awful is a bit of a stretch. There's a lot of teams in the country who'd love to have a QB that awful. His first year in a new offense and he had some hiccups. I predict he'll get some Heisman love next year early in the season, then it'll be up to him to keep that Heisman love going.
As for scheduling Big 10 teams, it MAY seem to be a more attractive option, but it's not a better option. The travel would eat into a chunk of that payout, and would limit the Cajun fan base from being able to attend those games. Sun Belt is 1-16 against the Big 10 with the average margin of victory being 23 points.
