Which defenders to field? Help

[bombers11]

Which two out of the three to field out of Scotland vs. Port, McKenzie vs. GWS, Birchall vs. Syd?
Whats everyones thought on Scotland vs the Power? I trade Scotland to O'Brien but would have to get Stanton instead of Beams which i'm not that keen on?

Scotland and Mckenzie!

No way I would be fielding Birchall. Swans were one of the first teams to put a tag on him. Should put on a suckfest.

Easy choice, bench Birchall. This year really hasn't been his at all...
