Jackstar - Rance was not on those players for the entire game. Especially Petrie, Rance moved onto him well after he kicked most of his goals, I think 4 were on McGuane, 2 on Rance. Against Freo Rance was credited with only having 2 goals kicked on him. You only need to look at the Dogs game and McGuane was given a 3rd string forward on Liam Jones who is 195cm and only played 10 games, where as Rance had to take the 200cm Minson who's played over 100 games and kicked over 60 goals.
Rance is not the problem down back, he has been given the big jobs over McGuane all season and for a kid who's only played 30 games so far he's done pretty bloody well considering he has no support down there. Now don't twist my words to think I mean he's been faultless, he hasn't, but he's show massive improvement and is definitely worth persisting with.
You are on the back of the wrong player down there.
