No, he would probably be playing a significant role in KHL by now, like Yakupov. At worst, he would be in VHL, also playing with adults. Like Gusev is.
CSKA is a special case, actually- they sucked at keeping their guys when they were tight for money and old management. So in that case, CHL is actually WAS a valid option, I'll agree. But things have changed and now it's far from perfect for Grigs.
My point still stands, he is stuck right now. I think when lockout ends he'll get a good shot at NHL.
And this whole, minimum minutes in KHL is ********. They are still with pros, they do their time and earn their respect. They develop in practices. Everyone started there, including Malkin and Kuznetsov and Tarasenko and Bure and Fedorov. It's not normal for NA, but it's normal for Russia.
