No one creates playoff avatars that are full of pictures and information that everyone can readily identify; there's a whole lot of team-specific [and at times, forum-specific] information in them. If you want to know more about it, you'll go do some research and learn some stuff. Or, you'll ask questions and get informed. Or, you'll roll your eyes and say "who cares, that's stupid." Either way, that team's fans will know what the story is and embrace it and laugh about it and roll on with it.
So no, no one else on HF is going to know who Bendak is at the start of this. If this team goes on a playoff run, he's going to be a near-HF legend by the time it's all over.
Actually, you could just have one frame with the W-L-T, the GAA under it, and the SV% under that, and then the next frame is Binnington looking totally serious with "must be the Cheshire Inn."
