Glad to see the NCAA respond positively to those mass marches, consumer boycotts and acts of Congress demanding this happen. What is that? Those things never happened? Well, I never (loudly clutches pearls)! 
I guess if a gambling firm or broadcaster (or gambling firm that "partners" with a broadcaster) is willing to finance these additional games then why should common sense stop it? Nothing builds a brand quite like exploiting and expanding it to the point of meaninglessness, right? Maybe the NFL should turn the Super Bowl in to a best-of-three series (think about it: more sponsor placements, more halftime shows, more eyeballs!)
At this point, they should just seed the top 16 teams and give them byes to the round of 64, then at random draw all the remaining DI teams in to a 300+ team bracket. That would be less demeaning than artificially expanding the field to include teams whose poor little feelings might get hurt by not being in the top 64.
