Defense failed because it banked on some tough odds - No Injuries, Mazi and Overshown would be Stars in Season One.
Let's be real... if Diggs, LVE, Overshown were all healthy. And Mazi came out like a first round pick, had a season more like Tyler Smith, we'd be balling on defense, even with our undersized, speed over size, win with the lead D.
There were other letdowns like Safety (arguably because of injuries) and Clark at LB, and Micah ain't winning Defensive Leader anytime soon with his crying on his podcasts, but we would have been closer to last year's D in how we finished.
