Riewoldt is 193cm which is key position size. 185cm is only an average sized midfielder in 2018. Look at the former great key forwards, if they are not over 192cm then they would not be great key forwards in 2018/2019.
Ablett was great at everything a key position player needs. Strong enough to outposition taller opponents, incredible burst of speed off the mark, a spring-heeled leap and a really good set of hands in any situation, pack, lead, one on one; and he could kick goals from anywhere inside 50 and roost em from outside 50.
Who knows if a modern coach would ever do a Blighty and send an aging 185cm player to full forward, but a guy with Ablett’s abilities and body type could certainly pull it off in today’s game.
