West was rubbish after 2011 and Simpson was playing in 13 until he got injured..Unfortunately falling out of favour is an ongoing issue with C Scott as the Coach. No matter what his form was in the last few games of the 2013 season, West was fit, uninjured, experienced, deserved respect as a premiership player-remember the premiership that only Scott could have won- yet wasn't played when Hawkins was a late withdrawal. Whether he was a genius ruckman or not he would have been a valuable addition on that fateful day.
Just as in this years finals round, a player is dropped for some reason or other non of which is discernable to us and others, forcing another player to fill in that spot. It didn't work in 2013 nor in 2019.
Another player who'fgell out of favour' was Dawson Simpson who dropped amark in a game at KP early in the season and wasn't seen again. Another one Zac Smith who failed to stip Gawn marking in the first game of the ??2017 season and wasn't seen again. Neither ever had a chance to gain experience for a reasonable decison to be made of their worth.
