Everyone is going nowhere.
I don't think Jethro is a good coach either, but a part of the DL problem is the scheme and positions. Tyriq should not be trying to hold the point of attack against a Tackle. The DL as a whole unit plays way too slow and terrible techniques.
Even on 3rd and long passing downs our DL are so timid in trying to play upfield and get to the passer. I know we don't have a Dominant DL group as a whole, but we should not be that bad getting pressure with 4 Lineman as we have been over 4 years. That's one part that has to change next year.
Depending how we finish the year. I could see Jethro and Paul taking the fall for the defense.
