Said it preseason, why not try Castagna. He is our best tackler, is one of our quickest, is very strong, played some minutes last week in the centre, and could quickly get off his man on a counter attack due to his speed and sharp movement. There is a question of footy nous of course, but why not give him a challenge. Worse footballers than him have become taggers.Is it time to try a tagger? They've never been more effective than they are right now. I don't get why Dimma is so reluctant to try it. Who could it be for us? Townsend? Graham? Personally I think Weller could do a good job. He's fast, decent tank, and lays a strong tackle. He'd be hungry, might be the last opportunity he gets at AFL level. If De Boer can become an elite tagger anyone can.
