So, one bad game and the system isn't that great? Sorry, but the NCAA Tournament is by far the most entertaining event in the sports landscape today. At worst, you aren't subjected to a month and a half long wait to watch two rusty teams stumble around for a half. At best, the tournament provides the best thing going during that first weekend with multiple storylines and entriguing matchups and endings.
Plus, if you are thinking Butler being in the title game last night demonstrates a weakness, don't forget how great a title game last year was. Just because the final throws out a dud in the end every once in a while doesn't mean the tournament doesn't crap all over the BCS.
