RSS to Links

Sorry if this has been asked for, but I am not really sure for what keywords or anything I would search for to find something similar to my question.

Well similar to how you sign up for a rss feed in firefox and links show up in your bookmarks (the titles and stuff) is their a way I can get an rss feed from like nba.com and make those links appear on my sidebar?

Basically nba.com has a rss feed on their news entries and I just wanted those links to appear on the sidebar of my site similar to how they appear in my bookmarks in firefox.
