Having watched it live from pretty much the top of the stadium it looked bad you could hear the impact thru the stadium.
Watching a,replay initially didn't appear as bad as first thought. Having watched his reaction he knew what he had done had it been unintentional then he would have shown some kind of interest offered a tap on the head or something to anakin, so I feel one game ban is a little light think 2 is fitting using an egp but a clever call not to use it.
