They run a lot of zone-read or read option, which is very different than the "option" that comes to mind when people hear the word, i.e. the triple option that has historically been used by the service academies.
In his limited snaps at QB the past two seasons, Q ran the zone-read probably 80% or more of the time, especially two seasons ago. It is a great play for someone like him, because he is a fast and physical runner, and since he is still learning the playbook, it is simple because it only requires one read: what is the weakside DE doing? If he cuts inside, Q will get to the edge and break off 8-10 yard runs all day long.
