Zimmer always has a well prepared defense that controls the run game and brings pressure in various ways, but he does play more zone defense, which is the trend in the NFL. Fangio’s defense of lining up in a 2- deep shell, disguising coverages and changing at the snap, bracketing the best receivers is the current trend. Martindale loves to blitz, loves to bring extra bodies and leave DBs in man coverage. Yes, Diggs and Bland are strong in man coverage.
If you want a happy secondary and more of what you had with Quinn, you hire Martindale. That means more emphasis on the pass rush, more blitzing, getting the ball out of the QBs hand faster, but it also hurts the run defense and leaves you vulnerable to mobile QBs because DB’s are running with receivers and not looking to the backfield.
If you want a more disciplined defense, better against the run, more fundamentally sound with less gambling, you go with Zimmer, and you get more zone coverage, which is the direction most defenses are going.
After posting a few responses about our choices at DC, I prefer Zimmer, but I’ll also hate it because every damn time I type Zimmerman (ugh), my auto correct changes it to Zimmerman. It’s driving me crazy!
