Australian Johnson was no stranger to delivering one-liners and colourful comments during his time in charge of Wales and the Ospreys.
And Evans does not anticipate a ceasefire ahead of Saturday week's Murrayfield encounter, saying: "He is quite a character really. He likes to put himself out in the press, trying to ramble some jargon and trying to play mind-games."
He added: "His worst fear is probably that he's coached most of the boys within our squad, so we will more or less know how his mind-set is.
"So he can ramble as much as he wants, it just becomes pretty boring in the end.
"Rugby is a pretty basic game, isn't it? I don't think you need to add fuel to the fire.
"There is no doubt that there will be (mind games next week). But, like I said, it's boring, for me anyway."
Johnson has guided Scotland to two Six Nations wins this season from three starts, which means they remain in title contention ahead of facing Wales.
And Evans added: "I am not surprised by it. He has been around international rugby with Wales and Australia, and he's obviously with Scotland now.
"So he is a very experienced coach, to be fair to him. He knows what he's doing and you've got to respect that."
