In Malkin's case he also has a Conn Smythe trophy as playoff MVP the year the Pens won the Cup.
Hard to overrate that factor when it comes to evaluating a player or his contribution to a winning team.
Leafs don't have anyone close to Malkin or Crosby when it comes to dominating a game and carrying a team.
Not so sure about that last one.
Maple Leafs have player who has also won the cup and even decided that cup in one game. His name of course is David Bolland. That guy dominates the game in a different manor and way than Crosby or Malkin. He talks to people and gets on their nerves while scoring stanley cup winning goals and other big goals at the same time. Deciding Stanley Cups is what he does as we all have proved. We all seen Bolland do his thing. He really does it all and wins at all costs and at all times.
There are different types of ways to dominate in hockey.
Carlyle dominates the game and other coaches as he makes them squat like a muther****er in almost every game. He also wins Cups while doing it.
Patrick Roy dominated the game by stopping almost everything and winning Cups at the same time.
Niclas Lidstrom played the game with fine hockey intelligence (putting the puck in very different places other fools would and also situating in areas other monkeys couldn't). He also won cups while doing this all.
Bolland, David controls and dominates the NHL while scoring some very important deciding goals and in the mean while playing fantastic defense and putting the small black puck where it needs to be. He also hits and makes very smart decisions in every possible way on the ice and off the ice. Malkin and Crosby sometimes don't do those things. They all win Stanley Cups, but dominate in very different ways.
