Ok players, coaches and refs, what calls are refs consistently getting wrong, and how can we use this board as a forum for better understanding of the game. Be specific.

Case in point: player A1 is attacking the goal of Team B and is in the penalty box in a 1v1 against B1. B1 then obstructs A1 so that his shot is wide. Ref blows the whistle and makes what call?

I'll post the correct answer later, but let's see how many know this one first. My point is better refs begin by better understanding the rules and spirit of the game.
