You are probably correct. I have no doubt he is.
I agree with ketchup that some things are better off "not said" or unprofessional. On the flipside, look at Tommy Biffle? Better yet, don't, no one needs to see those nutt-hugger shorts. LOL! He threatens everyone with verbal threats all the time. "Don't you fish my spot boy!"
Point being, you can say things that could be perceived as threatening and they shouldn't be said. Especially not with a big smile on your face and laughing when you say it so it's clearly meant as a joke.
Now in Watson's defense......if it were that one ref that is as cold as ice and has zero personality, I can't say as I blame him. I don't care for that ref either.
