I'm sorry, I just can't get behind the idea that Hornqvist is more replaceable than Hagelin. I think Horny's injury was a big part of why he wasn't with Sid later in the playoffs.
He's the heart and soul of the team IMO. His attitude and the way he plays helps drive the bus. If you are a young guy and want to learn what it takes to play playoff hockey, Horny is your guy to watch. He takes a beating and rarely, if ever, takes a selfish retaliatory penalty. I think Sully is a major reason for the discipline turnaround, but I suspect Horny is a big part of it too. Watching that guy take the abuse he does and just skates away is a team rallying cry (Sid is a big great example as well, obviously).
I'm not suggesting Horny is irreplaceable, but saying he's "blocking Archie and Rust" is pretty absurd to me. Archibald is a 4th liner with maybe 3rd line upside and Rust can effectively play the left and right side. I can buy an argument that Sprong is blocked, but I'm not starting him in the NHL anyway.
