Let's look at Rucks from 2010 to 2017. Keep in mind averaging 110+, but missing a lot of games, still counts as a failed pick, in my mind anyway.
Rucks that have averaged 110+, and how they performed in the following season.
2010
Sandilands - 19/114, followed up with 13/111, then 12/113.
Sandi started season 2011 with a bang. He went 8/123 up to Round 9 (Freo had a bye in Round 6.). Then wheels fell off. Questionable as to whether he was a good pick. Let's call it a line ball, given you were inconvenienced, and then forced to trade him.
After averaging 111 in 2011, he started 4/123 in 2012, but then you were forced to trade him.
2011
Cox - 22/122, and followed up with 22/112, then 22/107.
In 2012 his price quickly fell from an opening $662,600 to $542,600 by round 7. Starting without him, and then upgrading to him would have been ok thing to do. In 2013 his price drop wasn't so dramatic, but his output still dropped.
Goldy - 21/113, followed up with 20/93
Mummy - 17/113, followed up with 14/91
Sandi - 13/111, then 12/113 see above.
2012
Cox - 22/112, followed up with 22/107. Borderline success, given others were cheaper in 2013, but performed similarly.
NicNat - 20/114, followed up with 11/96
Maric - 20/113, followed by 19/97
2013
Goldy - 22/114, followed by 21/107
Minson - 22/114, followed by 21/93
2014
Mummy - 17/114, followed by 11/106
Jacobs - 22/115, followed 21/108
Martin - 12/112, followed by 20/111
2015
Goldy - 21/129, followed by 21/108
2016
Gawn - 22/119, followed by 13/92
2017
Kreuzer - 21/110 (109.8), followed by 12/80
So there you have 16 109.8+ seasons over the previous 8 years.
I'm just wondering how many are considered good picks the following year?
1, maybe 2, then another 2 that were "ok".
You say it is a limited sample, but 16 is a reasonable amount, and a 25% strike rate of being ok or better is pretty poor!
