When asked about his biggest challenge since transitioning to an NFL offense, Caleb Williams was honest. It is reading blitzes and making adjustments at the line of scrimmage. This is hardly a surprise. Defenses are incredibly diverse at this level and use all sorts of tricks to mask their intentions to blitz. It is why quarterbacks must constantly study film, looking for tells of when one is coming. Williams didn’t have to do that a lot in college because those defenses don’t go through the trouble of constant disguising.
