There's an old legal aphorism that goes, "If you have the facts on your side, pound the facts. If you have the law on your side, pound the law. If you have neither on your side, pound the table."

If I believe that and see someone pounding the table, I can make an inference about the ability of their position to stand up to scrutiny. I might be wrong in that inference, but IMO the lawyer with the facts or law on their side does their client a serious disservice if they choose to just bang the table.
