Again, DBJ getting the ball first means a hell of a lot in the interpretation of this collision.I was commenting on the beaten to the ball quite easily and chose to bump comment. They both could have marked the ball and Pearce didn't bump. Pearce's left arm is still out in your pic so hadn't braced.
BJs feet are off the ground too in that pic. Ball is a metre away
BJ not being aware of other players in front of him, put himself in a position where he has ended up with a collision.
Again I ask, what should have Pearce have done differently?
Pearce being late to the contest and not being aware of other players in front of him, put himself in a position where he has ended up with the collision that he could have avoided with a straight tackle for example. That’s where his mistake is made, and he may have to pay the penalty.
