The way I see it is Roberts is a symptom of philosophy change. As is our poor start.
I said something similar a few weeks ago Seibs expects your best every minute you show up. To train and on game day, everything about your game is measured and recorded. Hard conversations are had in systems like this because your failures are put to you to improve. Some people just can't deal with criticism, being constructive or not.
Roberts is one of these people. The moment it clicks for him and he stops looking for an easy out, his game will go to another level. Wayne didn't change Roberts as a person he was a crutch for Roberts.
Isaako may be another who has found the criticism to get in his head. His goal kicking has been poor and is an example of an internal struggle with doubt. The moment he frees himself from that doubt and realises he can be better he will be a weapon.
This probably can be said about most of our guys. Once the penny drops they can view their personal shortcomings as a challenge. They will naturally start to improve their overall performances.
Look at Offa and TPJ once the gap between their poor games and best games are nearly unnoticed they will be two of the best in the league.
Haas already has it and arguably so does Lodge, the next step for these two is to get better. The younger fellows will be the real winners here as they will have clear direction on what is needed. Staggs, Fleggler and Carrington are examples.
