the same time. Would be so hard for other teams to stop. You would have to think that one or two guys would be open every snap with Rex, Holker, Romney, Pauu, Nacua and Nacua all lined up with Algier in the backfield and or Lopini. Holy cow!
You would actually need to pull or rotate one of the guys depending on the formation and down and distance as you must have 7 players on the LOS, (which would include Rex and Holker), so that leaves 4, Hall being one so then have three more out of Romney, Pauu, Nacua, Nacua, and Algier and or Katoa or with one TE, could then use 4 of those.
With Hall's running ability he could be the defacto RB on occassion with no RB in the backfield (mainly just to escape pressure if needed)
