let's get everyone in time and in sync and executing the plays correctly and efficiently and THEN let's talk about options and audibles. it's way too early for improv. I would think AR knows that.
and, yes, sick to death of walking up to the line of scrimmage and running the play clock down to 1 second. OL gets no rhythm or power off the line and are on their heels cuz the D knows it's time to go.
get up to the line, have a look around, start a cadence and get after it. make the D respond to you for a change.
