One word: rebuild
Since our team wants to return into playoff berth, playoff competition and SB challenge, we must change a lot of what our past defensive-minded Head Coaches did.
This way Cam is trying to leave space on what he fells was unfitting into his offensive-schemes and adjusting an aging defense.
We may speak a lot about the defensive units of both Dave and Nick, because their main efforts were about it.
Their formulas were very similar : first step fix the defense; then upgrade your special teams and somehow make something at offense by leaving all the load into an amazing tailback (RW/RB), try to find the right offensive coordinator (Turner [D-]/Linehan [A-]/Murlakey[F]) and leave him rule the unit as totally different teams.
Cameron will change the focus. He knows that his mayor headache will be on defense because he needs a defense to stop the opponent and give the football into his offensive unit. His main role will be obviously fix the offensive scheme, while upgrading the defensive unit guided by Dom Capers.
Unlike his predecessors Cam is winning draft picks and clearing the house with Mueller as assessor.
My evaluation about McMichael is very simple, his skills are overrated because even he's an NFL star his fitting into Cameron's scheme would require a lot of discipline from him and with a 3 million bonus payment in door this was a necessary cut with very risky impacts.
The Welker stuff was pure business. An undrafted FA that became 2 picks is none common, so Mueller dealing is pure gold.
But the big difference will be the approach for the draft. Wanny wasted as much picks as he could, Nick was very close for what he knew while coaching LSU. Most accurate, best fitting, most valuable pick or another kind of tracking will lead the decision not just for a feeling but a scouting job.
