Fortunately North's recruiting staff are better at maths than you.Indeed, and it sets things up quite interestingly for the deficit scenario I've mentioned.
By my reckoning, if Scott goes before pick 35, and North match, they will be 'owing' next year and their 2nd rounder will drop accordingly.
As I've said, Collingwood is in a similar situation if they have to match for Kelly (in their case, it's before pick 39).
Not only did North not go into deficit they used live trading to move up next year's draft and picked up a surprise slider along the way.
