Under MyViews, Add a custom tab (name it whatever you want on bottom right). Now you go to the college football on the left, it will put up all available events. Click on the first one, then use shift and the down arrow to continue to highlight the games that you want. Hit ADD and then OK at the bottom right. It will be a completely new tab all the way to the right....you can mix sports too.
That's one way but it's a bit more complicated than it needs to be.
Just go to Setup up top, click on Tabs. From there you will see check boxes to include/exclude Added and Extra games in sports tabs, as well as include/exclude them from the Today tab.
