The NCAA passed several Football Rule Changes for 2006. Most of the changes are minor, but a couple that involve the clock may change the speed of the game. Most notably the Clock will now start on a first down as soon as the "ready to play" signal is given by the official. Studies indicate that this rule will shorten the length of time to play the games. This will likely change some strategy as the halves wind down, as you can't depend on a lengthy break after each first down, forcing more passes to be towards the sidelines.
