all Hocking has to do is ask himself what terrifies a defensive coach the most.
It's uncertainty.
What is the only avenue to certainty in AFL? It is the 15 metre chip kick. Very hard to stop it happening, because it's a trivial act for two 90 kg power athletes, and it buys you immunity from the opposition for 10 seconds, then another 10 seconds, and another.
It is that certainty that destroys the spectacle of any sport.
The mark needs to stay in the game, but the things we love about it (pack marks/speccies) aren't coming from 15 metre chip kicks. They come from 40 metre kicks, and we love them becasue their outcome is uncertain, the opposition has time to man you up, they could get the ball off you, but at least you went forward 40 metres, and could go forward again.
Risk-reward, that is compelling, that is what fans love in any contest.
tldr: it's simple, lengthen the legal kick length, reduce that avenue to certainty and safety, everything the AFL and Ch7 wants will follow.
Agree, make it 25 meters before a mark is called, otherwise play on
any kick backwards should also be play on
