This is an excellent point. With the way the CFL has evolved into a 70 - 80% passing league - half back is the most important position on a CFL defense.
It might still be mostly the same system - but ZC runs it a lot differently.
I mean, if it reverted back to mostly QB runs and check downs to the RB...the D would have to be very stout, and even then we might still lose.
The final result will speak for itself, just like it did in 2019.
Let them keep spouting garbage - and get guys like Biggie and Jeffcoat more even more fired up.
