Kicking xp prevents you from being in a even worse position though. You keep momentum, players keep confidence and everything. like its really not close tbh, you kick xp there. On another note, we dnt kick onsides if we were to get 2pt on our 2nd score.. im trying to think of anyway that the 2pt is justifiable there i cant think of any reason. Maybe if it was like 3 mins left instead of 9 we likely kick xp? Idk like reallyit's the only way to make the call - it's so obvious that it shouldnt be remotely controversial (because almost every HC does it this way now)
the reason you go for it the first time is really simple...
if you don't get it, you have more time to game-plan around not getting it and you know whether you need 1 score or 2 scores with more time to adjust one way or the other
if you kick the pat then you have learnt nothing, you still need a 2pt conversion, but now you've got less time to adjust if you dont make it
sure you've kept it a 1 score game for longer but that's meaningless if you're going to lose anyway
