Comes down to zone blocking vs man blocking with adjustments. From what I understand of Cables scheme, the linemen have lanes they are responsible for. 3 years now with so far no improvement and arguably regression. How about we change a coaching philosophy that is clearly not working.
We don't have the best personnel, and Bevells ludicrous long developing plays with no hot routes dink and dunk passing, around the edge rushing etc is putting twice the pressure on the line.
3 issues we have with protection:
1.)poor blocking scheme
2.)Zero compensation with offensive strategy
3.)sub par personnel
The FO could fix 1 & 2 if it had the balls, but we are limited on 3 due to cap and lack of quality lineman available. Our philosophy of defense first and keep the core players in O & D together is a good one, but you then have to make the adjustments for a sub par line.
Cable and Bev have shown they refuse to do this.
Let them go, can't really get worse playcalls or OL play than we have now.
