After the AFL changed the Match Review Panel to a single Match Review Officer in Michael Christian in late 2017, many expected a more clear and concise adjudication system in 2018.

However, these decisions caused real controversy among the public this season.

Here are some of the incidents that had the whole footy world talking!

8. Taylor Walker on Zach Tuohy

In their clash against the Cats at Adelaide Oval this season, Crows skipper Taylor Walker came under fire for this hit on Cats defender Zach Tuohy.

Walker was given a one game suspension for the hit, after it was graded as careless with medium impact.

Former Swans and Demons coach Paul Roos lambasted the decision, saying "when you slow it down, Iโ€™m staggered. This is the most mind-boggling decision Michael Christian has made all year."
