It's not a bad comparison.
Important to remember that Myers played for the defensemen factory in Kelowna though. He had two NHL defensemen in Tyson Barrie and Luke Schenn ahead of him in his draft +1 year, and the Rockets were still a playoff team. Where as Gordeev was Flint's defense last year on a very poor team.
But, I really would be shocked if he doesn't have a big year similar to Myers' breakout season (~40 points). Just don't expect Flint to win the OHL Championship like Myers did in his final juniors season...
