Yes, the defense is better.
Yes, the current CB play is better than the play from last year but far below what it was in 2009 when we were #2 overall in defense and up there in ppg allowed as well. This is despite eons better play from the ILBs.
My sole point is that I don't think we are getting the quality of play that you should get when you have a $50M CB on one side and a #6 overall CB on the other side. Ryan has been scared to blitz and leave his CBs alone because when he does we get burned through the air. The CBs need a lot of help to cover WRs. Now I wouldn't mind this if we had middling type investments there and had chosen to fortify the DL instead with a $10M player and a #6 overall pick but that is not the route we chose.
I hope I am wrong about Clai because we need him to become a shutdown type CB because of how limited Carr seems to be. He was beaten bad by DJax on his lone INT and Brandon Marshall absolutely abused him when given an isolation matchup. He is in his fifth year in the league so he isn't going to improve much beyond this point which is okay for a #2 type CB who you try to protect in your scheme.
