Steve Kerr makes awkward mouth gestures

Someone grab Golden State Warriors head coach Steve Kerr a glass of water. Or some ChapStick. Maybe even some gum. Perhaps some popcorn will suffice.

Whatever stops him from licking his lips like that.

Maybe this is Kerr's thinking face. Or it might be he's engaging in some mouth and jaw exercises. He could even be biting his tongue to avoid saying something he'll regret to the official.
