Two-point conversion is from the 2. PAT from like the 15 or something like that. So, when they got the offsides they decided to go for 2 from half the distance to the goalline (AKA the 1), instead of the PAT from the 10. It still doesn’t make sense to me. The 2 point conversion attempt would have been from the 7 after the Broncos penalty or 20 if they go for one. The Bears commit a 5 yard penalty, so that would mean either a 2 point try from the 2 again, or if it’s half the distance to the goal since the penalty occurred inside the 10 yard line than it would be a try from 3.5 yards out. Not sure why regular football rules wouldn’t apply here even if it’s a special play
