As a measure of speed I would equate getting to contests. On short viewing he seems elite at marking (pack & intercept) which to me says his speed is OK. Miller is quick but is vulnerable against leading forwards,so speed is also quick of mind. Happy for him to debut but is Carlton the best option for his development and confidence?I haven't had the chance to watch him play, but from observers he has been mentioned as slow. I take it he's a poor man's Brian Harris (Lake) type? If so you'd have to use a zone defence to help aid his deficiencies I think.
