Seabrook is slow, and is a right handed shot. Hamhuis is an excellent skater and a left handed shot, he also played with Weber for quite some time in Nashville. I'm guessing that's why they brought him - oh, and he's better than Seabrook. He also dominated the WHC last year.
Nash is one of Canada's best international tournament players of this decade.. that's the reason he's on this team. Jeff Carter is fast and a pure goal scorer, something this team needs. Right handed shot as well. Kunitz is not useless without Crosby and Marleau is fast and one of the better 2 way players Canada has. Babcock loves him because of this. I like Couture too, but obviously they're worried about his surgery.
Sharp, Marleau, Bergeron, Toews, Nash, Kunitz, Carter are all very good two-way players capable of playing shut down roles.
I feel like you don't actually watch much of anyone you've commented on.
Lucic on big ice? Christ.
It's pretty obvious they went for a team with big bodies that can skate & fill multiple roles. Their selections are pretty spot on if that's the criteria.
I actually watch a ridiculous amount of hockey with all players involved and followed the majority since they were in Jr. Nash is not good 2 way and is slower than Lucic and isn't as physical and has been kinda junk since going to the Rangers. I'd take Richards or Ladd over him for pure grit, compete level and momentum stealing and creating.
