One of my favorite blogs for keeping up with SEC football is Saturday Down South because they cater specifically to SEC football fans. They produce original content as well as aggregate news then ship it out to all of the major social media platforms so it is easy to keep up with. The editor in chief is also a former Division 1 athlete.
The Sun Belt Conference is not as large a force in college football, so coverage in the blogosphere is somewhat limited. Bleacher Report has a designated section about the conference with the same type of news updates and opinions that it has come to be known for in the sporting world.
