On a serious note, maybe captains can choose last tackle options when in oppostion half. Options could be Bomb, Grubber & find touch. Could be used if the opposition halfback has poor catching & jumping skills, etc.
The sim isn't retarded, I am sure it does that. There is way too much involved in this to decide every single last tackle option in the opposition half.
It's too specific. It would be more realistic to make it general aka choose the type of attack for the entire match and within that has the obvious plays.
Regarding kicks... I think percentages could work well, like when in opposition 20.. Bomb: 70% Grubber: 30% Sort of thing.
Looks good. That way you could choose the percentages based on your players catching/jumping/diving abilities.
