I'm saying that Rubtsov, Myers, NAK, and Ginning have nothing in common as developmental cases. Nothing. You cannot conjure up a connected theme involving those names. They're pulled out of a hat.
Rubtsov was wrecked with injuries, and his scoring never came along even at lower levels. He had pace issues and passivity issues. Before the Flyers even touched him, the signs were there in hindsight. I say this as someone who very much liked Rubtsov in his D-year.
NAK has done just fine for himself on the Avalanche and Capitals. He has been a useful ~25 point pace 4th liner. Now, we can discuss that the Flyers went out of their way to bury him in the AHL in the Hextall veteran craze years, with zero special teams time in 3.5 years. That he got more special teams time in the NHL his rookie season (after being call-up #12) was a sign something was off.
Ginning sucks and has always sucked. Nary a soul here, who watched him, valued him as a prospect.
Myers is among the best examples. Don't take my word for it: take the word of the POHO who called him a star (and we chuckled at that overhype). I watched him as much as anyone in the Q; I watched him plenty in the AHL. He was on a top 4 track. I think they went out of their way to neuter his best attributes and accentuate his worst. At a fundamental level, he did not resemble the Rouyn-Noranda version because, hilariously enough, they played more of an NHL system down there. He was fantastic at joining the rush -- that died structurally under Vigneault (just look at Provorov). Impossibly long breakouts did not play to his strengths at either pro level. He needed short support everywhere to manage his passing issues. He began to melt in the o-zone, turning into a turret. They tried to turn a hyper aggressive athletic beast into a safe player.

Now, the fact you have to preface a post with 3 paragraphs before giving me a reply, I'd wager to say you're right: I won't agree.
