You might want to think of doing a show for each specific season. You might want to do a football show, but that show doesn't need to run 12 months a year. Then when football's over, the same people (or different ones) might do a baseball show.
Those shows can be shorter, rather than covering *everything* in an hour, or hour and a half.
Or, you could do a weekly highlight show covering the scores and biggest stories in sports.
Just throwing out ideas.
