Disagree, in special forces training particularly close quarter battle, we used live ammunition at all times. You can train up to and including that sort of stuff the only thing that doesn't happen is people getting killed, we used targets instead, but it's as realistic as you can get and it gives a damn good idea of what to expect out in the field.
Richmond have got Jeff Bond supposed to be a "mental toughness" expert in sports psychology, from what I've seen of the mental toughness in the playing group, I'd say he's failed dismally in his 18 months plus he's been there.
You can replicate the pressure of a football game, scenario's like 5 minutes to go, you are 4 points down, come on we can win this etc etc. After all if you've got 40 odd players on your list, that is 2 full teams on the field, they should go hard at it. The only thing stopping such training would be the worry of injury to players, but to me that is part and parcel if you're worried about players getting injured in a practice game or training drill, then the players start to think that and back off, hence the reality goes out the window.
Richmond has been soft for years, physically soft and mentally soft, they need to toughen up in both areas if they are to have any hope of winning AFL games on a regular basis.
