I've not watched any of WI's games this year, but has anyone tried 4 DL and 4 LB's. If you are going to put a safety in the box all of the time and not respect the pass game, why not make it an extra LB. Then run blitz with the 4 DL and 2 LBS and keep a LB on each side covering the cutback lanes. Some risks involved....
Because that takes away all disguise from your D and also kills your ability to cover multiple WR sets or even good TEs. That's why its vital to have safeties that tackle well which we have. Travis in particular has the size and really plays like a Rover.
