There's plenty of blame to go around:
Jerry doesnt care about Defense. Lets be fair, especially on Offense we draft for need (or listen to DC), we/Jerry wasnt even that high on Micah, or we wouldnt of traded back 3 places. McClay shares in this Example 1 Mazi Smith (war room tape).
RevolvIng Door of DC - linked to Jerry, who doesnt care and tries to get his DC to do their best with limited resources. There's no succession between one DC signing and the next.......as is being said a good DC can get the best out of limited resources
Jerry/McClay 2 - look at how many of our Defensive draft picks get an extension (as compared to Offensive players).....from Quinn's DC era (a supposed involvement in the draft).....only Osa was retained.....says it all (even Overshown isnt a lock if his body doesnt hold up).
The players ARE TO BLAME if they cant keep their D-LINE gap integrity. or cannot make their personal tackles.
Eberflus is to blame for leaving 7th Rd CB's (Bridges) isolated because he wont give him any Safety help, then again who was playing Safety.......we were down to NOBODY LEFT = INJURIES HAPPEN. WHEN PLAYERS DONT CARE.
