I was more concerned about losing Mebane than Irwin but with getting a steal in round 2 in DT Jarran Reed and Clark's new physique I think we may have actually improved at those two positions. Overall, I have a strong feeling that the D will be better than '15. If we do lead the league in fewest points allowed for the 5th time it will be an NFL first and cement this squad's, and my, belief that they are the best D ever!
