When looking back at the history of McD’s defenses, they have been up and down. Pure speculation, but, by looking at it, it appears there is no adjustment on the fly. I did not dig deep and see which players were lost (if any) and strength of schedule but, at first glance it appears to be telling and par for the course.
Add in that each year he has been here we have had a lull in defensive production during each season and it begins to paint a picture.
Please don’t take me wrong: I am firmly in the McD corner as I believe, overall, he is a great HC.
