to me there are two issues to decide on when drafting players.
how good a player they have potential to be, and what are the chances they will reach that potential.
The second part is the hardest to get right, and probably the part we have got wrong too often in the past, or worse not even taken it into consideration.
garlett does look a likely type, but being from WA you have the extra in the go home factor, something probably even harder to gauge in advance.
all these things need to be weighed up, because all the potential in the world is useless if they aint on your list in three years time.
