Perhaps undesirable if you're picking a fantasy team but every team has to have 'em in the reality of the NHL.
No.
Neither the 2013 team nor the 2015 team had a Ben Eager.
The Frolik-Bolland-Kruger and Desjardins-Kruger-Shaw lines put the 2010 4th line to shame.
They had guys who were physical, its just that their physicality - whether they were using their body to protect the puck, or just battling guys like a pitbull in the corners or on the walls, or hitting guys, or battling for space and screens in front of the net - it was just one dimension of a multidimensional, useful player.
2013 Bickell could bang in front of the net. He could also corral the puck and put a shot on net within the square footage of a phone-booth.
Marian Hossa could use his body to protect the puck against anybody the other team put on the ice, without ever throwing a hit.
Jonathan Toews would just relentlessly battle for the puck and come up with it, even against guys much bigger than him.
Saad would just put his shoulder down, get his feet moving, and dare defenders to try and stop him.
Meanwhile, the 4th lines were happy to just take on top 6 competition, put the puck in their end, and put their stars in a blender in the corner with great sticks and a willingness to take punishment.
Toughness and physicality is an important part of winning cups.
The Ben Eagers of the world, who make it onto rosters because they pass a size requirement and are willing to get punched in the face for a living, are absolutely not.
