I think it's hard to have an every down back if you want to run tempo. I think a big advantage we could try to capitalize on would be having multiple players that can line up in multiple spots on the field. Imagine lining up with Robinson and Washington in the backfield, with Stoll on the end of the line at TE, with Spielman and Warner out wide. Then the next play, after no huddle, is Robinson in the backfield with Stoll in the slot on one side and Washington in the slot on the other. Then the next play its 5 wide. Then the next play is Washington in the backfield with Spielman, Warner, and Robinson all on one side. That would be a nightmare to stop without substituting, and by the offense not allowing them the chance you could end up with some real mismatches and a gassed defense.
What do I know though, except that this egg nog is delicious....
