At the end of the day there is the simple fact that we are now weaker in a number of key positions compared to last season and the season before that.
The reasons for this + the rights and wrongs regarding it have been discussed to death but simply put if you continue to lose top draw players and replace them with less talented individuals then your going to experience a dip.
We are now weaker @ Centre, Scrum Half, 2nd row and arguably, with the loss of Lima, Prop as well.
Add on top of the above we moved backwards at hooker when Piggy left and Tomkins is probably in his last season means there has and continues to be a systematic decline in the standard of players at WRLFC.
I don't claim to know how to fix it or also claim to be any more astute than IL but i do know that the above decline is glaring obvious and that's it's worrying/upsetting a lot of Wigan fans.
