The whole D started to improve as a unit starting with Bama game. Some of the D guys who were behind began to catch up and gave the D line a little depth. McCollough has been solid and gave us depth where needed and Shamburger became a different player. I'll just say that the coaching finally got through and now we need to keep that coaching in place for stability for next few years.
Let me also add that Bumphass, Kivon, Garland, Blakely have really started to come on. These guys need recognition for their improvement and contribution to the depth of our D line.
