Can i get stats such as these on assistant coach:
Kick chase metres(kick distance - distance returned by reciever)
Number of tackles it takes to score/concede a try from inside the 20m.
Try's scored/conceded next set off a penalty
Missed/ineffective tackles.
Number of play the balls per game.
The answer is no to all of them (except missed tackles) because, like I said earlier, the Dreamteam Assistant Coach detailed individual (you've queried a number of non-individual stats) stats are only those relevant to the game itself.
But what I've also discovered about the Dreamteam Assistant Coach is that the stats are displayed as Dreamtime points (as opposed to the real stats). So, in other words, they are pretty much useless to anyone apart from those playing the Dreamteam game.
As for most of your stat queries, those are some pretty complicated stats you're looking for. Nrlstats.com has some of them avaialable for free, but I'm not sure about the rest. Nrlstats.com, or some other paid for service, will have these stats, but I'm not sure how you'd go about getting them.
