From what Andersson himself has said it sounds like he was frustrated to not make the Rangers, maybe upset and not feeling like he was given a fair shot, and that he has a history of emotional outbursts and "spirals of doom" where he gets into self destructive behavior when feeling frustrated/down on things (in this case staying up late, not taking care of himself, performing poorly on the ice because of it, causing more doom spiral, etc) until he couldn't take it and went back to where he was comfortable and had family support etc.
Who's to blame? Dunno. Maybe the Rangers didn't give him enough of a chance, or maybe they were disappointed in his ability to play at NHL pace as has been hinted at. Maybe they didn't treat him well enough and support him or maybe he had unrealistic expectations and some personal issues to work out with how he handled it.
If there's more to it than that...then it's tough, you want to support your players but also not play favorites.
Ultimately, pretty weird.
I mean, Howden for shoving him into the NHL early but Hajek was playing in the CHL and went to the AHL and has played there for more than he has played in the NHL.
Eh, he rushed himself, and there's the complication of no transfer agreement between the NHL and KHL. When his contract expired in Russia he wanted to sign with the Rangers. It seems he got so hyped up thinking he was gonna make it that when he didn't it was rough on him, but he has regrouped well enough
