The Roosters lost to the Panthers in last year's Grand Final in wet weather, and he believes that if the Roosters face a wet weather match in a semi-final they could get beaten.
�We�ve got to play a lot better in the wet,� said Finch after speaking to ABC Radio after Saturday�s win.
�We could get (a game) like the grand final last year, a big semi-final could turn up wet, so we�ve got to play better.
�We came out with a goal of completing (our sets) in these conditions, because it�s such a vital part of a wet weather game and we struggled to do that.
This week the Roosters face the Storm in Melbourne on Sunday, and will have to play better then the last few weeks, else there could be a big loss on it's way for the Roosters.
