Brisbane and Wests the most impressive. Brisbane didnt have a down period. Wests came from behind against by far the most formidable opponent any of the top 4 faced. Manly's comeback was brilliant. Melbourne were lucky they were playing the knights - and equally lucky they get a home prelim final, but need to improve. Saints played greta - but will get no confidence from the luck of Wests victory. I think they will lift at Suncorp, and really test Brisbane. The Warriors? Who knows? If Big Manu wasnt so generous to the Broncos the score could have been very different.
I see the home sides potentially being troubled next weekend, but if they come up with good wins should have enough momentum to eventually meet in the grand final.
