I should probably have had one of these up ages ago, so sorry about the delay. Really this isn't the place for March Madness updates as I've already boycotted the entire damn thing. The team I was rooting for has since been eliminated. So College Basketball is dead to me.
But if it isn't dead to you, here are some Blogs I would visit:
Double T Nation has some quick and easy Tournament Reviews that should (hopefully) continue through the week.
A bit late with this link, but Burnt Orange Nation finished up its March Madness live blogging. The head honcho at that site, Hornsfan, also co-hosts one of the best NFL Blogs at SBN: Behind the Steel Curtain. Hogs Haven calls him a friend and I would consider it a personal favor if you would check out both his great Blogs.
Head over to Carolina March (UNC Tarheels) for more liveblogging.
Finally, Addicted to Quack (Oregon Ducks blog) has been updating frequently and will close out SBN's official March Madness Live Blogging around 4:00PM.
Can't hurt to visit Louisville's Card Chronicle at some point either, as I have been told it is one of the best new College Blogs throughout the Internet Tube Kingdom.
