FOS, I don't think it's about being too slow or strong enough. It's more an attitudinal issue. For example, Brayshaw is easily our best tackler and he is not that quick, and still only 18. But he commits himself fully to the tackle and usually gives a second effort if necessary. Some of our players are not committed and are too busy trying to corral their opponent, or they stick out a hand to make it look like they're making an effort. McCarthy and Kersten are good at that, and they're not alone.
