Ultimately, I think you're going to see a lot of 4-3 with...
Tuitt-Nix-Day-Ishaq
Jaylon-Fox/Carlo-Shembo
As a base defense this year with Shembo playing the SAM LB spot, Fox or Calabrese as the MIKE, and Jaylon as your WILL. It will allow you to bring the blitz with Shembo as necessary and you can occasionally engage Jaylon on the speed rush. I think you'll see Councell used a lot, especially in the 3-4 sets, because of his superior size to Jaylon... or if Jaylon can't hold up well enough at the point of attack on running downs.
