OK, not always. But a lot.
Other than that poor excuse for having to sell a call, I deem that there are times when selling a call is genuinely necessary and correct. Not to draw undue attention to the official, but to convey confidence and certainty on a call that, to the untrained eye of a subjective fan, could have gone the other way.

When an official gently puts his hands on his hips, it doesn't give me much confidence, either.
