I'm confident our collective hero Seth will have some breakdown and analysis of what this does to the depth chart, but for now Texas Tech loses one of its big men. And one of the biggest recruiting challenges in Lubbock as the 3rd (or 4th if you count Oklahoma/LSU as Texas vultures) premier school in Texas, is getting the big boys to come to the West Texas. Michael Starts never saw the field, nor did JJ Lollar and now one has the legitimate fear of losing Delvon's high school teammate Branden Jackson who looked to play an even bigger role.
The 3-4 is a scheme designed to stop the run with size. Until Texas Tech has someone capable of playing a Nose tackle and Ends that would otherwise be defensive tackles, this team will get obliterated in the trenches and allow opposing runningbacks to run wild. This is grim news. I haven't the slightest clue who replaces Delvon at his position or his dimensions. It might be more prudent to lean towards a 4-3 as the roster fits it better.
