These 2 websites will be very helpful for you. The 1st is a discussion forum that is more NCAA rules oriented than this one, although this one (Official Forum) has some great contributors as well. The 2d is a website built by former SEC official Rom Gilbert and it has EXCELLENT primers on various parts of the rulebook.
