I'm a HUGE Ovechkin fan, but you look at other cup winners in the past who had the "C" on their sweater (Messier, Yzerman, Brind'Amour, Stevens, *whispers* Crosby, etc..), they ALL led by example. I'm not talking about trying to do things on your own, because things don't work that way in the NHL. All of those guys on the road to their championships in NY, Det, Car, NJ, & Pit, each had a moment where their leadership came through in one way or another. I think we're still waiting for that "moment" with Ovechkin.
Remember, they used to say the same things about Yzerman back in his first couple seasons. But, I do agree that he needs to become more of a vocal leader.
