A chink in the armor? Bears need to get to Rodgers by exploiting Packers' depleted O-line
Fair enough. I still think the writer was aware of what he was doing, but I'll say it's on the outer reaches of plausibility that it was an innocent mistake. I'll also point out that all those examples show the phrase to be used in the context of a team otherwise thought to be unbeatable having a flaw exposed. As nice as the Knicks' run was, nobody thought or thinks they are the obvious favorites for the title.
