I reckon 18 points is a bit skinny, I'm tipping the tigers by 30, Melbourne should put up a better show this week and they did beat the bombers last year, 42 points sounds ok and Adelaide will beat Brisbane, no dramas there!
I think when it's all said and done, at the end of the day, football will be the winner and the winning teams will be happy to take home the four points. What do you mean by covering?
I think you'll be alright with that. No way St Kilda will beat Richmond same for Melbourne and Essendon (unfortunately) And Adelaide should easily beat the Lions if they play anywhere near they did last week
