He knew what he was getting himself in for so I see no point in now saying that it might all be too hard.
Why go through this whole thing then turn around and say this.
It looks like he hasn't cleaned up his act just as yet.
And why bring in others. Worry about yourself first then have a go at others.
If he won't comply to the rules which he would have know from the start then he has no place in footy.
He only has himself to blame but as always it is never their own fault.
And if he pulls out I would say he is still high on them what ever it is he had taken.
