our Dline is down for whatever reason you want to use- a fast paced offense makes it worse. The DLine being neglected has wrecked everything-now whether that is injuries/ youth / booting hill/ saving guys for Oline etc... is for other people to decide - but the D front 4 for VT has controlled the games and tempo of games for as long as I can remember. and right now ours aren't getting in the way very much
