If someone tries to bullrush you and take you down and you can clearly see the tackle comming. Before he tackles you lean over his body, kick your feet out from underneath you, so now you are on top of him and you just now countered THAT situation
In my opinion that is not good if you are outnumbered... Sprawling, being what is described above, will take you down to the ground, and thus less able to defend against your other oponnents who are still standing. Perhaps a throw would work better in that situation that way you are not vulnerable to other attackers. Thats just my opinion, any thoughts?
