WELCOME to Reaction Time.

Early each week, AFL.com.au's Riley Beveridge will discuss the topic that deserves a reaction at your club and grade it on the 'Urgency Index'.

It could be anything from an issue that's got a team pondering drastic change, or the form of an underrated star that requires immediate recognition.

The gradings, which relate specifically to the topics, are as follows:

• Panic Stations.
• Simmering.
• Watch This Space.
• Green Shoots.
• Flying.

In this week's Reaction Time we delve back into Saturday evening's Game of the Century and the moment that defined Brisbane's thrilling win over Hawthorn, and look at Fremantle's huge comeback victory against Sydney and the superstar Docker who turned the contest on its head.

You still have to kick the goal. Amid all the controversy, the chaos and the crescendo of noise that had engulfed the MCG, it's become a little bit lost just how clutch Hugh McCluggage was in going back and nailing the set shot with 18 seconds remaining. It was a huge moment, and Brisbane fans wouldn't have wanted the footy in anyone else's hands. The fact it came just four minutes after McCluggage had kicked a near-identical set shot to restore another Lions lead typified his reliability. After a season plagued by recurring calf injuries, McCluggage's three second-half goals added to a performance that also featured 23 disposals, six tackles, eight score involvements and two goal assists. Star.

That's why you go out and recruit Showtime Shai. All season, Bolton has been one of the competition's most clutch players and has consistently played a key role in the side's defining late moments. He did it again on Friday night. After being held to just 12 disposals through the first three quarters, Bolton went out and had eight touches and kicked two huge goals in the last. It added to a final-quarter performance where he also produced five contested possessions, four tackles and four score involvements as the Dockers overturned a 28-point deficit entering time-on in the third quarter. All eight of his disposals in the last quarter were recorded in the forward half, while he also had a goal assist. Champion Data now has Bolton as the second-highest-rated last-quarter player in the AFL this year, behind only Ed Richards. Already a two-time premiership player in 2019 and 2020, expect Bolton to add to his glittering Grand Final legacy next week.

Is the Jarman Impey situation not completely nullified if his Hawthorn teammates immediately become the third, fourth, fifth and sixth men into the contest and lock the ball in? Jai Newcombe, Massimo D'Ambrosio, Lloyd Meek and Josh Ward were all within touching distance of the contest and could have joined the tackle to ensure the footy was held in and to give Impey no way of disposing of it. The holding-the-ball call was 100 per cent correct, but frustratingly for Hawthorn it also felt 100 per cent avoidable. Hawks coach Sam Mitchell gave an insight into his own irritations around the incident on Monday morning, calling his players "stunned mullets" in the pivotal late-game moment.

The Freo Flash has got plenty of full-strength sides this season, let alone a severely undermanned Sydney. There was always a sense the Swans might struggle to hold onto their early lead and, indeed, the final-quarter stats told the tale of the contest. The Dockers had 17 more entries in the final quarter, won clearances 12-5, and also won 22 more contested possessions to kick the last six unanswered goals of the game. The Swans, on the other hand, didn't hit the target after the 16-minute mark of the third term. While it was a gallant effort, going all the way always looked a step too far for this version of Sydney.

FOOTY ASIDE …

The mid-tier of the Premier League has never been stronger, smarter and savvier. This weekend had Brentford beating Chelsea 3-0, Brighton thrashing the league leader Arsenal 3-0 and Fulham holding Manchester United to a 1-1 draw after limiting Liverpool to a 0-0 stalemate last weekend. While the big dogs like Chelsea, United and Tottenham are languishing in the bottom half of the table – Spurs on the very bottom, for their part – the likes of Brighton, Brentford and Leeds look set for a European push heading into the upcoming international break. The rise of the mid-tier is a credit to intelligent ownership models and organisational structures, as well as the consistent gambling on youth and on less-traditional markets in the transfer window. No giant is safe these days.
