I don't think he was really given a fair shake in Montreal to be honest, which looks to be a reoccuring theme with younger prospects over the last decade. But hey, Julien doesn't have patience for Russian players it seems, so it was likely never going to work out anyway. He would rather call up AHL lifers like Agostino and Chaput than give Scherbak even one second of playing time this season to even increase his trade value.
Also, less than 30 games is just not enough time to declare a 1st round pick a 'bust', especially one who had some pretty decent numbers in his last season in the AHL. Scherbak has a lot of offensive skill. I hope he is given the chance to develop the other aspects of his game in LA. It will be an uphill battle considering all the time he's missed over the past 4 seasons due to injury, but the potential is still there I believe.
Claiming him and giving him some playing time was an absolute no-brainer.
