In this post I looked at some 2014 defenses, including S&P's no. 1 rated Clemson, and noted how they used Norm Parker's cover 6/fundamentals-focused approach to choke out college offenses.
Few things really expose a college quarterback like trying to beat cover 2. However, having a boundary corner who can hold up against the run game is a prerequisite to playing this defense on non-passing downs.
Kansas State and Texas are the two teams most likely to be able to regularly employ that strategy in 2015 although TCU is surely hoping to find a boundary corner that can allow them to mix it in.
