It depends. Burke gives Gase another card to play next year. Gase has become masterful at stacking excuse cards. People don't change.
If he has enough traction with Ross that TB prevented Burke from building the defense he needs, then Burke will be spared. And Gase can continue to tinker with his offense.
Burke can blame Suh's contract, Branch's injury and the bad Harris pick as reasons for the D being bad against the run. He also can show marked improvement by the new LB core. X's development and Minkah's promise. Burke has a ton of excuses available.
If Gase thinks Burke can be spared and used next year, Burke stays.
Also, have we not identified this draft as being DL heavy? Can you see how this can be used as ammo to save Burke and give him one more year?
