If Ben Griffiths can get the body right, so he can get a good run at it, he be a very good player for Ricmond.
You dont lose your ability and from what I've seen he is quick, good below his knees, spring heeled with good hands. brave and can kick 70 metres. Big blokes always seem to take a bit longer and I cant really think of any that have domininated in their first or second season.
It must be a hard / disapointing to suffer set backs in your development but blokes like Cotchin kept at it and even when Richo was still around they rated Jack below a C grade bit is now very good.
