My initial gut instinct was that it was a penalty but I wasn't 100% sure. Which I think is the point Wes is making. If you're not 100% sure then its not "clear cut" IMO. Semantics I guess.
Does a referee have to be 100% sure before giving penalty decisions or do 'the rules' give him leeway to award a penalty based on a percentage certainty?
It doesn't really matter how "clear cut" a penalty is upon fine tooth comb scrutiny. Its how "clear cut" it was to the referee in real time.
