I often see this on myself and my oponents. I always try to trust on my opponent judgement so i have some peace of mind. Also when i have a little doubt on a ball i dont call it and keep playing. Christopher October 8, 2015 at 4:52 am - Reply Funny video. This reminds me of a question I have about the etiquette of questioning calls. A fellow I play with occasionally calls "wide" my shots down the sideline that are clearly in by at least 3-6 inches (not a "deep" baseline situation) when he is on the other half of the court. Several times I have challenged him when I have had a view directly down the sideline and he has ultimately reversed his call, but am I wrong to challenge his call, particularly when I KNOW the shot was in from my better vantage point? I feel bad doing that, like I'm accusing him of cheating. Am I out of line there?

When I asked to see the mark my opponent said it must have evaporated. Oh well.
