I totally disagree with this D. We have tried this the last few years. It's too complicated for the new guys. You need a team like NE that has been together forever to be successful. Their core has been there a long time and that is why you can plug a new guy in and it still works. We have NO core! We have guys like Crowder who couldn't find his way out of a paper bag. We DO NOT have the personnel for this D and aren't even close to having it.
I see the Vikes and their 4 man front and that is the way to start a D. You put 2 BIG tackles up front and dare the other team to run on you. Once you shut down the run now you get a decent set of DB's and a top safety and now you can make things happen. Your LB's can now run around and do damage. You make the D so complicated nobody is on the same page at all times. The only way this works is IF they bring in ALOT of players from that system. It will take 2+ years just to get these guys comfortable and how much turnover will take place in that time and then guys you teach - will they still be here in 3 years the way FA is.
