How about now? 11 years is quite a bit of time to have a big sample size of results. I don't think never getting out of the 2nd round is what I would call great results. Ovechkin is very much a "Ewing" type if you ask me.
I think Ovechkin is an odd bird in terms of the "Ewing theory."
To me, I don't think he is a prime candidate because I honestly don't believe the Caps are as good or better without him. Remove Ovechkin and the Caps are a far less dangerous team. The opposition heads into every game focused on containing Ovechkin, especially on the PP. When teams do this, other Caps draw weaker assignments and have more space to operate. Remove Ovechkin and the Caps aren't nearly as scary.
That said, I think Ovechkin is the ultimate "secret weapon" come playoff time as opposed to "franchise carrier" (aka Gretzky, Lemieux, LaFleur, Orr, Richard, Howe, etc.). Ovechkin reminds me a lot of Brett Hull in that regard - he's a nuke bomb who can be kept under wraps but the fear of detonation is always there.
Ovechkin can't carry the Caps on his back come playoff time. He's not a centerman and his game isn't versatile enough to make him an impact player if he's not scoring, like a Forsberg, Toews, Bergeron, Kopitar, Gainey, etc.
To me, a guy like Rick Nash is a "Ewing Theory" poster boy. All sizzle and no substance... regular season and even worse in the playoffs. Remove Nash, his game, and his salary from your team and you're better off. You can accomplish the same or more with players that have far less raw skill than him. This isn't Ovie for me. Ovechkin is a legit difference-maker... it just doesn't come as easy in the playoffs.
