Millsap is with A as the primary but can be run opposite with D as primary. this play flipped has been called Toe's Mom.
B-D clear deep. A needs to set up a cut with all the space cleared and get the disc underneath. The more you can drive your defenders hips upfield and then go horizontal the better.
B comes under on the home side, and D comes underneath on the away side. Both have the agency to cut their routes off and go through the middle if it's open. C makes a double move and is the deep look option.
Hit someone on an under or a deep look. Continue to attack the endzone.
