Not sure who knows about this website, but I find it fascinating. You click on a team, then you can choose to see their record vs. other teams or conferences. For example, here is Akron's record vs other conferences: (
http://mcubed.net/ncaaf/tvc/akron/index.shtml) You can then select that conference and see who they beat, the score, the year, etc. It's a really useful tool to check some teams history out.
