Because it was also "...did represents childish cowardice and a cynical, brutal attempt to cheat the game. It's a vile, repugnant thing to do anywhere in society and absolutely does not belong on the football field."
Lol one season ban, smh.
I don't know why you seem so focused on comparing this only to other incidents on the field.
It's an incredibly flakey and limited defence or excusing of a player on the basis of "Well player X did Y and got banned for Z so.."
Raking your elbow down the back of another player is hot headed, stupid and potentially dangerous. It arguably cost his team a crucial game which eliminated them from the competetion. I haven't been keeping track of Song's punishment but hopefully he gets one that fits the nature of his stupidity.
However, I don't think that is compareable to biting another human. At all. And I don't know why you seem so focused on trying to draw such comparisons. If you don't understand why a professional adult
intentionally biting a competitor
for the third time in his career while showing
no understanding or remorse for that is different to a horrible tackle or a silly elbow down a back, then I don't know what to say to you. I really don't.
A 5 game ban for that would be woefully short and woefully ineffective of disciplining a man with an ongoing track record. He would do it again.
