A run where the tackle is the puller, usually to a linebacker, while the rest of the line zone blocks. The counterpart to counter, with one puller instead of two.
The backside tackle pulls and leads up through the hole, usually onto a linebacker, while the rest of the line blocks zone. It gives a downhill run a lead blocker without asking a guard to leave the interior, which is the trade that defines it.
