Yeah you can offload, I haven't quite figured out the timing but it seems to be that you have to hit the pass button immediately upon impact with the tackler.
Another thing, it looks like the player does do a bit of a step when you hit the evade button so both step and fend are the one button, the step doesn't really work but because of the good player control if you line up with the left or right of an opposition player and hit evade while turning away sharply it seems that this effects the step or fend better than when running straight at them and trying to barge through.
I will say that I was surprised at how good the kicking is, in some ways better than RL1 and 2 in that there is no slow motion and you still have time to kick as the defence holds off a bit to keep their line intact.
It's a neat little game for what it is, you just have to have very very low expectations going into it.[/b]
