Why would anyone NOT go for 2 when you're up 7, especially with under two minutes left? Yeah if you kick the extra point you force them to go for 2, but if you convert your own 2 the only way you lose is the opponent scores, recovers an onside kick, and scores again (one of the scores being a touchdown) all in under 2 minutes or whatever would have been left, and with no timeouts. If you don't make the 2 point conversion, you're still up by 7. In an era when coaches quite often nonsensically go for 2 at a time when if they don't make it, they lose the game, you're telling me it would be a bad idea to go for 2 at a time when if you make it you win and if you don't make it, you're still up by 7?
EDIT: Well I guess the thinking is if they score a touchdown, BC could then go for 2 to win it, which as I've beaten to death here, would be the wrong move but has become seemingly conventional these days.
