They must have read my post in another thread on this.
In all seriousness, Slater is an elite, highly skilled sportsman. Your chances of getting someone like him to adapt from Rugby leauge would better than that of Gaelic Footballers.
He knows how to "break the lines" and could teach most AFL players a thing or two about tackling.
If he could be taught how to kick and handball properly you would have a more than handy player, with plenty of attributes such as leadership, big game experience/performance.
Any club would remiss in not at least considering the idea.
The biggest knocks would be his age -27 this year, but would still have 4-5 years left in him possibly- and whether he could build up a tank big enough to play Aussie Rules
