The simplest solution is...you only get one pick in the first round...that should apply to every club always...unless a club gets a 2nd pick for being consistently sh*te for long enough from the AFL.
That would stop all the BS trading for points, splitting draft picks and most importantly guarantees that the top end talent is spread evenly across all the clubs....which was supposed to be the entire point of the draft.
That is basically what I'm saying, haha. If you wanted Campbell, use your Pick 4 to draft him. If you don't want him and you'd rather McDonald, you don't get two bites at the cherry. Simples
