Jarred Hayne is probably one of the most heavily scrutinized players. Sometimes it all becomes ridicolous.
His Origin game showed what kind of player he is. He is one of the games elite players that much can't be doubted.
When he was at parra he was the whole team. It was up to him to do everything. That would be why his stats were better at parra. He was also responsible for a large number of freakish plays. But that pass the ball to jarred and expect him to do everything approach came at cost, parra didn't make the finals in his last 5 years there.
When he first came back, the criticism was that jarred was trying too hard. That he kept getting the ball at the detriment to ash Taylor. That titans had falled trap to, 'give it to hayne and it will happen'. So then he seemingly tried to take a step back and let the likes of Taylor, elgey and Roberts take control. Then he is accused of being dis-interested, not taking control etc. His love-hate relationship with the media doesn't help. He can be accused of not having dig and also trying to much and getting in the way of the halves in the same game sometimes.
At his time at parra he never had anyone feed him quality ball, he never had anyone that can take control of the team so he can focus on his own role. Slater has smith and cronk for example. If titans can get Taylor Roberts and elegey running things then use Hayne on top of that then they will be a danger side. But it's gonna take time to develop. Meanwhile everyone wants hayne to take over and do more, and that would be to the detriment of the Taylor, elgey, hayne combination.
