i like to run that as a man/zone blitz
try it this way sometime
(note: i have Lbs at the DE position)
1. universal all LBs into zone, put the ROLB into a purple
2. man up the DE on the left side of the screen on the HB
3. bring the blitzing saftey over next to the DE, and reblitz DE and DT
4. user whoever you feel like it
good pressure and coverage
