Boak.
Mundy's disposals record against Port Adelaide is one of the worst.
He averages 19.4 disposals per match in his career, but just 17.2 per game against Port Adelaide.
Last year he only got 19 disposals in both matches against Port
STATS
Boak averages 22.3 games per match in his career, but 19.9 against Fremantle.
Last year he racked up 22 and 23 possessions respectively in the matches against the Dockers
STATS
Even with the possibility of Crowley, you have to go Boak. He's in career-best form.
That's my best Merc-stats attempt.
