Malkin doesn't lead Ovechkin or Crosby at this point.
If you watch Malkin, then actually watch Crosby, you'll see that their playmaking and vision is NOT equal. Crosby is ahead, especially when you consider that his skills translate to the NHL.
When you watch Malkin and watch Ovechkin, it's plain to see that AO has another gear that Malkin simply can't keep up with. No way he matches AO's natural goal scoring ability either. He hasn't shown that ability yet.
As for strength, I think anybody who has seen a lot fo Crosby will tell you, his lower body strength is astounding. He is incredibly hard to knock off the puck and when he has the puck, he uses his body incredibly well to shield it.
Malkin is an impressive player, Crosby and AO are simply on another level though. Isn't Malkin older than Crosby also?
