In speaking with my 'source,' Team A has to 'declare' their intent to attempt a field goal or score a touchdown on a Try. If they intend to attempt a field goal, then the ball is placed at the B-15. If they intend to attempt to score a touchdown, then the ball is placed at the B-2. An otherwise legal place or drop kick made after they have declared their intent to attempt to score a TD - that happens to pass through the uprights and over the crossbar - simply has no point value (even if the ball is snapped from the B-15 (or behind)).
If the try will be repeated following a penalty to either team, Team A can re-declare their intent. If they choose to attempt a field goal, then the penalty will be from the B-15. If they choose to attempt to score a TD, then the penalty is enforced from the B-2. But, again, if they declare they are attempting to score a TD, then they cannot get any points by kick.
What I forgot to ask (and I will try to ask) is: If they declare their intent to kick a field goal, can they fake the field goal, or advance a kick that fails to cross the NZ, and score a 2-point TD? I don't know, but logic would say they could. But, in 2022, there is not much normal logic to the NFL.
They are intent on 3-hour and 5-minute games. Competition be damned. Gotta make TV's window. The on-field guys are simply guessing at what they want with respect to roughing the passer. They are between the proverbial rock and a hard place, with directive to protect the QBs, but then getting criticized - externally and internally - when they make a RPS call. The fear of repercussion if they don't call RPS is stifling. But, when they do, social media explodes, and then the 'league' throws the referees under the bus.
Social media, and, now, the highly public betting industry, is killing NFL football.
