i understand where you are coming from the the "confusing the opponent" but in softball we call for balls to keep another fielder from running into the person calling for the ball. If players stop listening to the calls for the ball then we are going to see some terrific collisions causing some concussions or broken bones. It's for sure a player safety issue. That's why it's bad sportsman ship in one sport but not in basketball. No one ever got hurt by passing it to the wrong team or giving up a rebound.I wasn't asked to do anything unsportsmanlike, either. My point is "confusing the opponent" was not considered unsportsmanlike. Pushing someone out of bounds when the ref wasn't looking is unsportsmanlike. Elbowing someone down low when "fighting for a rebound" was unsportsmanlike. Clapping your hands while they were trying to shoot or pass was not. Yelling "same team" or "ball" or "rebound" wasn't. Never was considered unsportsmanlike when I played. This was the same "type" of thing as yelling "mine" to the infielder. Again, different sport. Different rules. It's unsportsmanlike to break rules period.
