Saints have been in the media all week about how they are all dissapointed with each other and how they need to really start playing proper footy etc.
No doubt Brown has drilled into them that this is a make/break game for both their season and for him as a coach. They have a LOT to play for.
I'd imagine the punters saw this as a chance to get on them while their odds were down - only when that many punters do that the odds slide, right? (not the biggest gambling man, but I think that's how it works...)
Anyway, it's a good chance to get on Manly in a mutli. Find some safe bets, add manly in there at 2.40, throw on 10 bucks and there's a free night on the drink!
