He is not until he also struggles in the KHL. If he goes to the KHL and has an OK career...then he earns being an OK player. Likewise if he goes to the KHL and actually finds his game again and becomes somewhat of an elite player in the league.
Hell, I could see him going to the KHL, becoming a star in the league for a few years, then attempting a comeback much like Radulov did in his late 20s. (not exactly the same situation or player types...but the comparison holds)
Yak outwardly at least did all the right things in Colorado. I actually liked flashes of what we saw of him and he at least looked like he was trying most of the time on the ice...just he never found a fit once Duchene went full trade mode and it was worse once Duchene was eventually traded.
Heck, if I am Ottawa, I would talk to him and see if he won't give being on Duchene's line another go.
At the least he was not disruptive in the Avs lockeroom and seemed to be a good guy. Part of me would not mind him signing another contract with the Avs -- as he was a decent depth player to have around. Though he clearly will be looking for a team where he can play regularly out of the gate of course...so that won't happen.
I think there is a right situation on the right team where he can be a decent NHLer....but the fact is once Colorado made the shift from being a 2 line team into a 1 line team after the Duchene trade, he was worthless. Yak needs to be on a line where someone else carries the load and he is third fiddle on the talented line. He will never drive a line in the NHL....nor can he be a part of a balanced line that works with 3 players of equal talent and ability working together. He needs to be carried to a certain extent, and thrives in that role.
