Can you name those other 13 players, Rowsus? That's great insight all round, especially that it only took 12/14 players to their 5th season to reach the 100 mark. Sort of like if they don't hit the mark early, then lightning wont strike twice again.
In no particular order, the 14 players are:
Pavlich - joined in 2005 with 111.2, this was his 6th season of AFL, but it was the year SC started. We can't be sure he wouldn't have joined the 110+ Club earlier, if it had been available. He has one better score, 115.6 in 2007.
Chapman - joined in 2007 with 112.8, this was his 8th season of AFL, and once again we can't be sure what the seasons prior to 2005 would have produced, SC-wise. He has 2 better scores, 119.0 in 2009 and 116.4 in 2010.
Judd - joined in 2005 with 114.5, this was his 4th season of AFL. He bettered this score 3 times. 131.8 in 2006, 118.5 in 2010, 115.5 in 2011.
Mitchell S - joined in 2005 with 110.1, this was his 4th AFL season. He bettered this score twice. 113.4 in 2011 and 110.8 in 2012.
Swan - joined in 2009 with 123.2, this was his 7th AFL season. He probably wouldn't have made the Club in his 1st 2 seasons. He bettered his joining score twice, 126.9 in 2010 and 126.2 in 2012.
Ablett - joined in 2007 with 114.2, this was his 6th season, and as with others, we can't be sure what 2004, and earlier would have brought. In fact, I have been trying for 3 years to find his 2005 score! He has bettered his joining score in all 7 years since, by at least 12.9.
Goddard - joined in 2009 with 115.5, this was his 7th season. His only better score was in 2010, with 130.2
Murphy M - joined in 2009 with 112.9, this was his 4th season. He has only bettered this once, in 2011 with 118.0.
Selwood J - joined in 2009 with 110.9, this was his 3rd season, and he has bettered it every season since.
Pendlebury - joined in 2010 with 110.5, this was his his 5th season. He has bettered this by at least 13.9 every season.
Goldstein - joined in 2011 with 113.2, this was his 4th season. He has bettered this only once, with 113.5 in 2013.
Rockliff - joined in 2011 with 113.6, this was his 3rd season. He bettered it last season with 132.0.
Bowden J - joined in 2005 with 110.1, this was his 10th season of AFL, but the first of SC, so we can only guess when he might have joined. He bettered this twice with 125.1 in 2006 and 117.3 in 2007.
Cox - joined in 2005 with 111.8, this was his 5th AFL season. As with others, we can only guess how his earlier seasons faired. He bettered his joining score twice with 122.2 in 2011 and 112.3 in 2012.
It's definitely an inexact science, given SC is only 10 years old, but there is no doubt a correlation between the earlier you break the 110 barrier, the more likely you are to do it again. Sort of commonsense anyway, I guess.
