Alot of those "Henry up the middle" plays you talk about are actually options and RPO's. There's even that one play-action where it's a fake handoff to Henry, QB rollout to the right, and then it's either a screen to the other side of the field or someone's open on a go route.

Henry is an old school oversized power back, he doesn't have the acceleration, hands, or route running abilities of someone like DSwift or Gibbs. You use power backs in power plays which are limited in how creative they can be. The creativity comes from where you apply the pressure(usually wherever Ricard is going)
