At Port v Fremantle, Mark Ricciuto tellingly observed: "Have a look now - you can't see on screen at the moment." And he was absolutely right.

"They were famous a couple of years ago for their foot use," Gerard Healy noted of Port.

He probably meant kicking, as opposed to mastery of the Hokey Pokey, or some variety of exotic juggling.

Hawthorn stalwart Luke Hodge took a turn in the booth for Channel 7 at the Melbourne-v-Carlton encounter, observing: "Melbourne have gone back to that six-six-six structure." This was quite the revelation, or at any rate seemed to come from the Book of Revelations.

Well, they do call them the Demons. But maybe Luke is just partial to Iron Maiden's sprightly ditty of yesteryear, Number of the Beast.

Meanwhile, there are early season hints of a pleasing new AFL broadcast tradition.

The setting this time was the Geelong v North post-match interview with Joel Selwood, in which the Cats captain summarised: "To their credit, our boys did a f---... a fantastic job. I apologise for that - I'm pretty emotional right now." Interviewer Cam Mooney laughed, the boys in the booth laughed, and you'd imagine most home viewers managed at least a smile on the strength of it.

The point here is that's twice in two weeks that Cam Mooney has got sworn on, following Paddy Ryder dropping an even more resounding clanger right on top of him in Round One.

Australia hasn't had a truly reliable source of televised sporting swearing since the winning jockeys in the Melbourne Cup used to F-bomb freely every year during the post-race horseback chit-chat - a tradition that, disappointingly, seems to have fallen by the wayside in more recent times.

Frankly, if Cam Mooney can act consistently as a lightning rod attracting top shelf profanity in these careworn times, a grateful nation can only thank him for his sterling efforts.

Otherwise, Season 2017 footy coverage is not starved for imaginative uses of the language.

Brian Taylor, Western Bulldogs v Sydney: "By no means this 21-point lead is absolutely nothing at the moment." So far as can be decoded from that, it was or it wasn't, in as much as 21 points can ever be equated to nothing, exactly.

Seven's Hamish McLachlan can always be relied on for his somewhat disconcerting way with an unorthodox metaphor. At Melbourne v Carlton, he described a player's failed attempts to break a tackle: "He bit off a lot, chewed hard, but couldn't get it done." Hopefully this wasn't the kind of circumstance which led to something 3AW's Bruce Eva, at the beginning of the Bulldogs v Swans final quarter, fearlessly if unappealingly described as "a secondary throw-up".

Same station, same game, and the redoubtable Tony Shaw took the points for the week.

"Aliir Aliir's got athleticism - the unknown factor." More of a known factor, you'd think.
