It's looking more and more likely that McCarthy wants to change the packers defence from a 4-3 into a 3-4. By firing the entire defensive staff, it would allow the new defensive co-ordinator to bring in guys that know how to implement the 3-4 system straight away rather than waste time teaching the current staff about the 3-4.
Whilst some packers fans question the wisdom of making that change, i dont see the problem cos our defence cannot get any worse. We were so bad that we couldn't blitz, we couldn't stop the run and we occassionally gave up big passing plays. We were very predictable and teams knew what was coming and adjusted to that.
I've read that having a 3-4 defence is cheaper than having a 4-3 defence. If that is true then it would make good sense as it would give us the flexibility to improve other positions and even improve squad depth quality.
Also out of 32 teams, i've read only 10 of them plays the 3-4. That would give us a advantage during draft day as the demand for players that fit the 3-4 system is lower.
Another advantage, someone on here pointed this out, is that with the 3-4 you can stock up more guys who is suited to special teams. They have the size and speed that McCarthy likes in special team players. The 4-3 don't have as many of that type.
I would LOVE the packers defence to be very aggressive, in your face and implementing exotic blitzing schemes and constantly pressure the QB. I LOVE watching Pittsburgh simply because of their defence and if we could do half of what Pittsburgh do, that would be an achievement.
The biggest problem in changing to a 3-4 is the players. We will have players who are a bad fit for that system. It doesnt really matter as most of the players isn't very good and will have to be cut/traded anyway. We will use our 9 draft picks (maybe more if we trade any guys away) to bring in guys that fit the system.
If Miami could change their team around so dramatically, Green Bay can do the same for their defence. That is my optimistic view.
Getting Suggs would be a good starting point. He's only 26 and knows the system well.
Of course, to ensure the success of the system, we need a dominant NT. Pickett is a good starting point. What you may have forgotten is that we have a player on the practice squad who has the size to play in that position. His name is FRED BLEDSOE. He is 6ft 3 and weighs 329 lbs. It's possible that McCarthy was planning to make the change for a while and picked him up in anticipation of that change.
In the 3-4, the outside linebackers, i feel we may already have some players who could adapt to the system and be a success. Not necessarily as a starter but as a valued squad member. Danny Lansanah is of similar size to Harrison of Pittsburgh. Could he play that role? Jeremy Thompson has great size and athleticism to play the other side. If you compare them to other OLB from Pittsburgh and Baltimore,
Harrison- 6ft and 242 lbs
Suggs- 6ft 3 and 260 lbs
Lasanah- 6ft 1 and 248 lbs
LaMarr Woodley- 6ft 2 and 266 lbs
Jarret Johnson- 6ft 3 and 270lbs
Jeremy Thompson- 6ft 4 and 270 lbs
They are certainly the right size to play in that system.
So size-wise throughout the whole defence, i can see why McCarthy feels we can change the system as we do have the players available to us to make that change. Not necessarily the quality of course.
