Yep, I've got a fair idea. No doubt Jesse had some issues to overcome, he grew up in a rough house, slept on the floor in the garage, was around drinking consistently, started himself early, it was written in the stars that he would grow up an alcoholic. So you feel like he had a lot to overcome through no fault of his own.
And yeah, his mates were parasites. Scum. They showed no interest in helping him get better and fulfill his promise, but Jesse wasn't smart enough to drop them, either. As for half-arsed support, Jesse got as much as NZC could give him without attaching themselves to him 24-7. He had a psychologist, Karen Nimmo. Minders regularly followed him out, as early as his NZ Academy days. They overlooked a whole barrage of incidents no one heard of, for a long time. They tried, and tried, as much as anyone who isn't an AA leader and aren't trained to help alcoholics (these are cricket staff, remember) could have. Ross Taylor did his best, but lost faith. Brendon saw the good in him but knew the culture couldn't sustain it. Mike Hesson tried, everyone did. Anyone who thinks Jesse Ryder was dudded, I feel like you'd want to appreciate how much was done for him before it all became too much to deal with, and the needs of the team ultimately won.
