RSS Help

Hi, I have been fumbling around building my site for a couple of weeks and I finally have a problem that I can’t find an answer for. My site is sports oriented and I am trying to set it up so that I can organize a bunch of rss feeds into categories and sub-categories allowing me select news feeds for individual teams. I would like to pattern it after something like this. I have set up categories for the sports leagues I want to track and sub-categories for the teams in those leagues. I get drop down menus showing the teams-so far so good-I am using Yahoo Pipes in order to bring in several feeds at a time-which is also working, but I can’t find a plug-in that will actually insert the feeds into a post (I have tried several that say they do, with no luck). I have tried using widgets but I can’t find one that will allow me to use drop downs.
Any help would be greatly appreciated.

P.S. I use the Suffusion theme.
