Hey guys. I'm new to the site and have been a Jets fan my whole life. But it wasn't until 2 seasons ago that I really started to get into the intricacies of football. Could someone write me a detailed explanation of Rex Ryan's defensive system, and how it works? For example, what is meant by 5 technique, cover 3, cover3, dime, nickel, etc. . . And could you also recommend things to look for in a game, I feel like there is much more to appreciate abut this beautiful sport. Thank you.
