I see your point here. Our senior players and whole 22 have consistently failed in big matches during this 'window'.The issue I have:
2015 SF - had a really bad day
2016 R23 with top 4 spot on the line - had a really bad day
2016 SF - had a really bad day
2017 GF - had a really bad day
2018 - had a really bad season
Seeing a pattern there?
Our finals record since Walsh's appointment:
2015 EF - narrow win
2015 SF - big loss
2016 EF - comfy win
2016 SF - big loss
2017 QF - comfy win
2017 PF - comfy win
2017 GF - big loss
I guess this group of players peaked in 2017. As a fan I desperately hoped they were still good enough to 'go one better' in 2018 and clung to the hope that the squad was still a granny-worthy squad this year. But now we need to look to 2020 and beyond.
