Rubtsov has shown nothing. At this point he is barely a prospect. He's almost definitely a bust.
He is playing in the top six on a KHL team and shutting down the best players in the league every night. His D game is not an issue at all. He is a good PKer. Good on the boards. And has a lot of skill.
Will he ever be more than a bottom sixer? Probably not. Frustratingly so. He has the tools. But a very defensive mindset. He thinks defense 1st, 2nd and 3rd.
Ratcliffe was worse than him in the AHL last year. Put up less production, playing easier minutes, while being a worse defensive player at a less important position. And he cant PK well. And his IQ seems lacking. And he struggles with short area skating.
And he is only half year younger basically. And has LOTS of issues to figure out. Heck, he is less physical and worse on the boards than Rubtsov despite being a lot bigger... is half the defensive player, and has worse hands and vision.
If Rubtsov had been a 3rd or 4th rounder and was playing "fine/well" in the KHL like he is people would probably be higher on him.
If Rubtsov is barely a prospect what does that say about Ratcliffe right now? He needs improvements in a lot of areas of his game. Big year for him coming up. Because right now he is a sub-par AHLer who was outplayed by basically every other forward prospect last year including Pascal Laberge.
