The extra-point try is one snap for the game on the line. You want your highest-percentage rub or fade, a play repped so many times it works under pressure. These are the calls that steal points when it matters most.
The return rub frees a receiver clean at the goal line, the highest-percentage call versus man.
A two-way go: fade to the pylon or the hitch underneath, the quarterback takes what the corner gives.
Three routes into one defender is the safest read in a short-field, one-play situation.
Isolate your best receiver on a slant and win the snap.
A rub like the return concept. It frees a receiver clean at the goal line versus man and is the highest-percentage call for a single high-value snap. Rep it so it works under pressure.
It depends on your league point values, but a well-repped rub or fade converts the two-point try often enough that many coaches go for it when they trust their play. Have one automatic call ready.
Pick one or two conversion plays and rep them every practice from the exact distance your league uses, so the team can run them automatically with the game on the line.
