I am the owner of the Mississippi State Sports Blog. I inherited it from Travis a few years ago, moved it to a new domain, etc. Travis did have a new blog started, but it has been pulled offline for some time now. There are 2 pretty good basketball blogs out there as well.
I can speak from experience that it is tough to balance a full-time job, family, AND keep up a quality blog about anything - especially when it doesn't pay anything. Sure, I have ads, but they don't generate much.
This past football season was probably my most active with the guest blogger q/a posts and the SEC Power Poll voting - although I even missed the last 3 or 4 weeks on it. I focus mostly on Football because t is hard to cover sports like Basketball and Baseball that have so many games being played each week, where Football is one game per week.
I think if you could put together a group of devoted fans that could rotate posts, you would have something golden - similar to what EDSBS is doing.
