I called this but its not like its some prophetic concept. When you have players with unique talents, as a coach, it is your duty to find ways to maximize those talents. For all of his potential, Irvin is a bit square peg. Raw, and with some weaknesses. Add other legitimate pass rush, then stand him up and. Move him around and create uncertainty which creates hesitation and hesitation is lethal as with Irvin's speed you're already playing catch up and voila.
I would not be surprised to see innovation in the back seven as well, at times. Be it bandit or something similar. We just have too many special skill sets and our coaching paradigm is too innovative.
