Always bet on Crosby showing up when the spotlight is on. He's a Gamer that's for sure and I'm not referring to video games. Just as in 2010 it was easy call to pick Crosby as the Golden Goal scorer in OT and of course he didn't disappoint.
Glad to see Marner decided to shoot there. I've always viewed it this way (I was a pass-first guy too whenever I played hockey, it was natural as I had accuracy in my intent), if you can pass the puck accurately, you can shoot it where you want it more accurately too. He picked the top corner on that shot like he shot 1000 times against a cut-out goalie in his driveway. It's not always a slapshot that fools a goalie (though it helps).
Hopefully some of Crosbys commitment to winning when it matters most rubs off on him when he is there. Mario learned a great deal being around Gretzky in the '87 Canada Cup and he took his game to the next level when he saw how much Wayne wanted to win.
You can't just sit back and rely on hockey skills training, you have to dig deep and will your team to victory. Mario could easily outclass his opponents as did Wayne, the difference was Mario saw hockey as a great paying job that he was just naturally great at while Wayne loved the game (and loved to win).
Once you turn that corner, it's downhill.
