My GBA490 professor advised us that if we were ever going to steal money, STEAL BIG. His reasoning was that if you stole a few thousand dollars you were going to get caught, put on trial, conficted, and put in jail. If you stole a million dollars the company would be too afraid of having their stock price crash and they would sweep it under the rug not really worrying about you.
Gus Malzhan and a number of other coaches knew many of their plays were technically illegal but they were betting that if they ran it fast enough and they did it often enough that the refs would either be unable or unwilling to see it or throw flags on every given play. They knew they would occasionally get flagged but they also knew they would sometimes get huge game changing plays that they wouldn't otherwise get. They just played the numbers game and won. They probably knew the gig would be up this year, my guess is they have been looking for other weaknesse to exploit. It's sort of sad that this sort of attitude passes for OK in our society. We allow anything from anybody as long as they win, are rich, famous or beautiful.
