There's a push on to play four games at the same time at Jerry World next November as part of the NCAA's salute to troops.  Bad idea, for all the reasons outlined in the article.  They would outdo Barnum & Bailey by one ring.  Sounds like something ESPN would get involved in just so it could do all four of them at the same, one on each of its networks.  This might not be the dumbest idea in the world, but it's among the top 2.

Kill it.  Kill it with fire.

Basketball in a football stadium is always a bit odd anyway because the seats are so far away from the court and players have real trouble with depth perception.  And I'm sure they'll figure out a way to put all four games on Jerry World's giant screen, which may serve as a distraction to fans, players, coaches and officials.  Not to mention the need to have four different PA systems capable of reaching into the stands so fans can hear but without bleeding over into the other games.  Plus, in a 100,000-seat football stadium you're going to have tons of empty seats, which will add to the acoustics issues.  Most important, though, what's the point?  If they want to honor the troops, why not give them an opportunity to see all four games in their entirety instead of bits and pieces the way CBS covered the NCAA tourney for 20 or 30 years.

How would they keep the whistles from one game from affecting the other three?

I'd rather not turn marquee NCAA games into one.
