watch De La Salle, they pull the weak side G & T to the strong or TE side on a counter, QB reverse pivots fakes hand off to RB who scraps heels of pulling tackle, then hands off to other RB who chases pulling tackle.
As far as pulling both and only having center cutting off chasers this would be situational "is the DT over the pulling OT charging? bearcrawling, have 2 gap control?"
