To join fellow BtBers in some bracketology brain-busting, click here. In addition to bragging rights, we're giving away a prize to the winner: a $15 gift certificate to What If Sports, good for one sim league. What If Sports is a cross-era simulator for all the major sports. They have some free demos you can test out and a well-named blog with articles based on their sim engines. Rumor has it that WIS is pretty addicting.
If I remember correctly, Yahoo limits leagues to fifty entrants, so sign up early!
SBN plug: We have a blog dedicated to the March Madness tournament, Blogging the Bracket, and a ton of college-centric blogs. Check 'em out.
