1. Disgraceful Blues hit rock bottom
The stats told a shocking tale for Carlton. On the night the Blues celebrated the 20th anniversary of their last flag, they were utterly humiliated and suffered the biggest loss in the history of the club - which started playing games back in 1897. The 138-point massacre eclipsed the previous low against North Melbourne in round 22, 2003 by 14 points. The 4.11 tally was Carlton's lowest-ever score against the Hawks (previously 36 points in round nine, 1971) in 162 matches, despite the match being played in pristine conditions under the closed Etihad Stadium roof. It was the largest margin ever between the teams (previously 128 points), while Hawthorn fell seven points short of their highest-ever score against Carlton. For good measure, the 26,815 crowd was the lowest between the clubs since 2000.

2. Irrevocable damage done to Barker's coaching hopes?
As the Blues' horror show unfolded, interim coach John Barker must have been wondering if he was watching his chances of leading the club beyond this year disintegrating before his eyes. The Blues were humiliated, falling to their biggest half-time deficit against Hawthorn (65 points) and worst loss. No one expected Carlton to seriously challenge, but this pathetic offering was the first time Barker has failed to inspire a fighting effort in seven games in charge. A season-ending round 23 clash with the Hawks could be telling. 

3. Should the AFL put these two teams back in primetime?
We've become accustomed to quirks in the fixture, especially involving Carlton this season. Still, it seems incredible to think that the Blues, who have lost all six of their Friday night games, could play again on the big stage when they front up against the Hawks again in round 23. Speculation has placed the floating fixture round as likely to see the two clubs meet again on Friday, September 4 at the MCG to best advantage finals-bound Hawthorn. For the sake of neutral fans' interest though, does the AFL need to think twice? 

4. Star Hawk walking the Match Review Panel tightrope
Josh Gibson is likely to find himself on the brink of suspension after an off-the-ball hit on Blaine Boekhorst in the first quarter. The Hawks defender whacked the unaware Carlton youngster in the stomach, leaving Boekhorst hunched over on the ground. It was similar to Gibson's shot on Adelaide small forward Charlie Cameron in round 12, which earned him a $1000 fine and a 'strike'. The dual premiership player will almost certainly be just one incident away from a third 'strike' and mandatory one-match ban after the MRP reviews this round – not ideal heading towards finals. Blues Nick Holman and Liam Jones could also find themselves under scrutiny for late and high second quarter hits, with Holman reported for his hit on Luke Breust.

5. 200 games later and Murphy's still searching for a win over Hawthorn
It must rankle the Carlton captain that on the night he became the 34th Blue to reach the 200-game milestone, he suffered yet another thumping from Hawthorn – a club he has never beaten. Murphy arrived at Ikon Park via the first pick in the 2005 draft and, despite enduring some of the club's darkest days, the 2011 All Australian and best and fairest has given the club great service. Murphy was his typical hard-working self on Friday night, collecting a team-high 36 touches. But the way things are shaping up, he might be searching for that first triumph over Hawthorn for a few more years yet.
