yep. you're right.
the volume of ignorant horse**** about QB play spewed on this board is enough to choke a donkey.
new rule for the CIS hoi polloi: unless you played and coached the QB position in college, please STFU and let the grown-ups talk. you're embarrassing yourself and your family, along with irritating most of the people you sit with on the bus bench each afternoon while waiting for your ride to work.
as a point of fact, there are multiple concepts in pretty much EVERY passing system, that REQUIRE "single read."
spoiler alert: the system gattis is running has them.
additionally, most reads are done pre-snap, so even when there are (in SOME cases) multiple reads for a particular route concept, post snap, there is only ONE read. are there progressions that require scanning through primary and secondary receivers? of course. but that's often based off of a SINGLE POST-SNAP read, and how many progressions there are in the pattern totally depends upon the system and concept you happen to be running. if you want TVD to have more post snap reads? great, send a letter to gattis and tell him. i'm sure he'll be happy to hear from you. it will also make the passing concepts more challenging for the receiver, but that's ok right? these guys have shown they can handle anything we can throw at them.
