Just want to check myself, on the Nickel formation with 4 Dline, the DE seals
When BYU has 4 Dline on its Nickel formation it appears that the Dline has seal on the end. When they are playing a 3-4 setup the OLB's have outside contain.
Thats what I think BYU is running the majority, let me know if and what I missed.
