If Flynn goes elsewhere, Tolzien will get first look, with some 7th rounder stashed on the practice squad. The Packers like Tolzien's arm and are planning that a full off season and QB school will make him a decent backup. They had figure out quickly if Tolzien won't cut it so they can bring in a street vet in time to learn the system, just as long as he is not Seneca the elder.
I think the newest CBA makes an offseason QB school illegal.
