His talent, production, and international pedigree heavily (heavily) outweigh Schingoethe. Not to mention he's .1 years younger than him too and MHL > USHL. I know you're lower on him than virtually anyone on this site, but he's without a doubt in a higher tier than Schingoethe, who I actually like too.
I dont think he's our 13th best prospect (I have him somewhere between low in the 3rd tier/early 4th tier), but I think you're almost at the point with him (with all due respect as you know I respect your opinion) where you're pulling a Keith Law that no matter the information given or what the player does, he's nothing.
Schingoethe is 16 days older than Ovchinnikov. They are practically the same age.
Ovchinnikov barely has an international pedigree. Some U17 games and 2 U18 games is hardly an international pedigree for a European, given the amount of international games they play. 31 different Russians played more U18 games than Ovchinnikov that year, and 12 other guys played 2 games as he did. Schingoethe likely would have been on the U18 squad himself had there been an opportunity for him to play in those tournaments, and may have a better chance at a U20 squad for the USA than Ovchinnikov has for Russia (given Schingoethe can play a defensive specialist role, while Russia has a ton of better pure offensive talent than Ovchinnikov at their disposal).
Ovchinnikov has more offensive talent, but Schingoethe is significantly better defensively and can play center. Ovchinnikov will be able to play higher in the lineup if he makes the NHL, but in terms of overall importance and making the NHL, Schingoethe has the clear edge.
Not really sure the MHL is better than the USHL, but even then, Schingoethe is now in the NCAA while Ovchinnikov is still stuck in the MHL. NCAA >> MHL.
Putting Ovchinnikov in the Schingoethe range does not mean he is nothing, but all I am saying is there has been little evidence that guys like Ovchinnikov turn into anything. I've read the scouting reports, I have watched the highlight clips of him, and I have watched a handful of games. His production is nothing special, especially for the Eastern Conference of the MHL. He should become a good KHL player some day, but I can't say that I have not see a dozen other Russians just like him over the past few years, most of which have gone undrafted and have not really made NHL teams regret it. We are effectively hoping he can turn into another Gusev, who has a very similar profile and career path, but Gusev has looked a lot better at 20 than Ovchinnikov, and he was a D+2 7th round pick who is currently fighting for his NHL life at 29. I am not going to write off a 20 year old guy, and I guess it is better he puts up PPG+ production in the MHL than not, but he needs to bring a lot more to the table to turn into a legit prospect, and is closer to turning into another Kara, Kizimov, etc. Schingoethe is a long shot too, and his lack of production is concerning of course, but as a defensive specialist to begin with, and where he is at in his career, there have been a lot more guys like him who have become productive NHLers than guys like Ovchinnikov.
I guess I am just tempering the expectations a little bit with our Russian prospects, because I have done the research and it does not look favourable for any of them except Amirov. We are effectively hoping these guys become exceptions or outliers, like Mikheyev, than the bulk of Russians who have eventually become NHLers.
