MIles' true opinion of our Defense

I wonder what degree of concern he really has over the continued poor pass coverage of our DB's and LB's. Does he see it as a major problem like most? Does he recognize the degree of vulnerability we have when McCray is in the game as a nickel/dime in cover situations? Does he proportionately recognize that our LB's have been out of place on pass coverage for a higher percentage (yes, this happens to every team, but ours is inordinate) of times per game than a truely good defense? Does he see that Mallory and Peveto have carried over the same basic pass coverage ineptness from the 2006 and 2007 Pelini defenses, who struggled mightily against all of the decent pass offenses we faced and shut down the slow or running based teams we faced to creat the Pelini image of a strong overall defense when in reality we are very vulnerable to a balanced offense or a passing offense?

Just wondering what he really thinks. We have been lucky to overcome this consistently, but it will catch up to us...
