Here are some I can think off...
1) Tall guys can't make steals - the myth here is that it isn't their job so if they don't do it, who cares? This might just be the most naive myth of them all. As we saw last week and then again yesterday, steals are a massive momentum stuffer. Glasgow could barely put their heads above the parapet last week and they'd lose the ball. Connacht suffered a similar, if not as exaggerated, a fate yesterday. The idea that fetching is the job of one or two specific guys is a complete nonsense. We see two meter tall guys like Francke and Venter regularly stealing the ball while also doing the rest of their job. Fetching is everybody's job. From Cronje to Crappies, Venter to Francke and SJ...every steal is priceless.
Let's, for once and for all, call utter bullshit on the myth that fetching is for some and not for others. It's highly valuable and everybody should contribute where they can. And the more you fetch the more valuable you are.
2) The pro game is too congested for expression - It's not just the Lions that have made a mockery of this myth. The Champions Cup, thank heavens for the Frenchies, have shown that space is a product, not a commodity. The most recent high quality rugby I have watched has proven that. The in form sides in those competitions all create the space and then exploit the space.
Kiwi teams always created space in SR and dominated us by doing that. Champions cups teams do the same and the result is the same. The Lions are doing it too and the results are showing.
By extension, the myth of a 12 needing to be a donkey brain crash baller that kills all momentum is dead.
Creating and exploiting space will always be the most effective type of rugby.
The congestion myth is nonsense of the highest order.
3) Offloading is too risky - This statement might be true if the benefits of offloading were not as clearly voluminous as they are. To be considered "too" risky, we'd have to see far less returns yielded from a strong offload game. Again, all the most recent high quality rugby I have watched has shown that the less you offload the less likely you are to score. In fact, I'd go so far as to say that offloading in contact is up there as probably the highest return exploit in the game. I'm speaking from a touch of bias and an imperfect memory, but I think one would have trouble proving me wrong.
I know I have picked all the low hanging fruit here. So perhaps not left too many obvious myths to be busted...sorry haha
Are there any other myths you can think of that the Lions and Frenchies have busted this season?
