Run Gurley at 'em. Then run Marshall at 'em. Then run Gurley at 'em. Then run Marshall at 'em. Lather, rinse, repeat. Occasionally catch 'em cheating up to the line by hitting Bennett or Conley behind 'em. Or, if he's got his head on straight (TEAM, not ME), hit Quayvon to keep 'em honest and punish the backs. But above all - use your strength (which is a great running game) and that should HELP to neutralize their strength (which is a great pass rush).
On defense -
1. Get off blocks.
2. Wrap 'em up.
3. Bring 'em to the ground.
4. NO BLOWN COVERAGES!
