stack vs zone read

We have had more success running it spur to pitch and lb to q, unless the q is a bigger threat in the open than the pitch. We found it helped keep our read for the spur more similiar across offenses and it we just didn't have the speed for the LB to get over the top to the pitch man, most of the time the q is running close to off tackle and the pitch is wider, if we got a shot on the q often our lb hadn't gotten out to the pitch man yet.
