It isn't beyond the realms of possibility that there is no draft this year. Word is it is highly unlikely any form of NAB League will be played in 2020. List sizes reduced going forward is going to leave a number of players without clubs so the need to top up lists with draftees may not exist. I think there is every chance the 2020 draft will be canceled. There are a number of problems for this year's draft and next years' if things are not changed. Drafting players with no real exposed form as 18 yo is risky, and the 17 yo bottom agers will have no real form guide for 2021. Good luck using their 16 yo form as a guide for their u/18 year. It is looking likely the draft age may rise to 19. There are supporters for it in clubland, and two with AFL ties being Brad Scott and Paul Roos. The time to do it is now given all the variables as this results in the draft maintaining some semblance of integrity whilst not disadvantaging any players. This is one of the areas that are really intriguing as to how it may play out.
Think 19 is an awful idea as it will make players choose between work and sport. Many potential AFL players will give up between 18 and 19 as they start going to university or go to work.
