I'll eat crow if I'm wrong, but I'm really quite certain anybody who can see "Crunch Time" right now, will be able to watch the game live or late tonight watch it in the archives. I think even watching content from the archive section means you can watch ISU tonight, the A&M/ISU game is still archived and maybe a few others.
This game will be a 200 to 1 outlier in my ESPN3 experience if it's not on there. I watch about 5 games a week on espn3 between college fb, college bb, nba and soccer. If it's in upcoming, it means it's upcoming on espn3.
Now 2-3 years ago ESPNU really did mean "never on ESPN3" which is why I can see people thinking it's not going to be on there.
I've never had an issue, either.
I'm also pretty sure that my parents watched the OK State game earlier this year, which was on ESPNU, through ESPN3.
