Brad Scott has got the North Melbourne Football Club on the same page in 2018, and the results are showing.

The Roos have recorded big wins over flag fancies Sydney, Hawthorn and GWS, and nearly took the Tigers all the way at Etihad Stadium.

Jack Ziebell's move forward has been a masterstroke, while Ben Brown has emerged as the premier power forward of the competition, leading the Coleman Medal after nine rounds with 31 majors for the season.

The kids are contributing too, Jy Simpkin and Ryan Clarke are doing work at opposite ends of the ground, holding down the Roos in both the forward and back line, respectively.

Maybe the most impressive showcase this season is from Ben Cunnington, who has been playing elite level football and is thriving within coach Scott's current system.
