North Melbourne coach Brad Scott fears constant rule changes by the AFL will hurt the game North Melbourne coach Brad Scott is concerned that the game is being hampered by constant rule changes. North Melbourne coach Brad Scott fears rule changes will hurt the game. NORTH Melbourne coach Brad Scott fears the game will become "unrecognisable" if the AFL continues to tinker with rules. Scott is opposed to the 80 interchange rotations cap to be trialled for the first time in this weekend's NAB Cup second round. I'm concerned a little bit that the premise is incorrect in the first place. I'm not sure that we should be trying to tire players out to try and reduce congestion," Scott said yesterday. You go back and look at the evolution of the game. In the early 2000's you had flooding; 2010 you had the opposite with players pushing to the other end of the ground. The coaches evolve and alter their tactics based on what's presented to them. If we cap rotations and fatigue players and make it difficult for them to get around the ground, we'll just adapt, we'll just change the game again. If our players are really tired and we're getting scored against and we're opening up, we're likely to just put 16 players behind the ball to stop us being scored against. If we make rule changes every time there's an evolution in the game, we'll just end up chasing our tail. I feel for the AFL because they do the best they can to trial things in the NAB Cup. 'But the reality is we're playing shortened games and, when you cap interchanges at 20 (each quarter), the quarters go for seven or eight minutes less than the regular season and you find most interchanges happen late in the quarter. So are we going to get an accurate set of data? I doubt it, but I don't know what the alternative is. Scott said the Kangaroos want to continue its winning habit against the Gold Coast Suns in Townsville in the NAB Cup second round on Saturday afternoon. One player unlikely to make the trip is cult hero Majak Daw, who developed swelling in the knees after North's wins against Melbourne and Richmond on Friday night. Scott said the ruckman-forward would need to improve rapidly today to be guaranteed a place in the 24-player squad. That (swelling) was disappointing given that we managed his loads through the pre-season and thought he would get through. And we managed his load in the games, so at this stage at best he's 50-50," Scott said. Scott said Daw's running goal against the Tigers instead of handballing to teammate Brad McKenzie indicated how much work was still required on his "fundamentals" to complement his eye-catching athleticism. "We're trying to simplify the game for him at the moment," Scott said. Nathan Grima (back) and Leigh Adams (shoulder) won't be risked for the trip north, but both are on track to be ready for North's Round 1 clash against Collingwood.
