Not sure on that matt. The freeze part Was mostly to draw in defenders on a play where they think it’s a fb run or option run with either the qb or hb, if not then it’s a “freeze” play with qb drops back for a downfield pass after presenting an option look.
The fullback part of the option was a quick hitter type play, and the option the qb had was to hit it himself when opportunity presents, and if not pitch to the hb.
As my posts back then suggested, That’s exactly what I thought we should have done this year and go back to the future old school when Angeli went down.
