we probably disagree on what Hedman is. for example, Muzzin scores just as much as he does at even strength, and does better defensively in tougher usage.
But if you are saying trade Marner for a super elite dman, again, I'm listening.
but note, Tampa only won when they had 1) impact ELC players in #2C Cirelli, #3D Sergachev, and #4D Cernak and 2) when they had a fluke cap situation that allowed them to keep an extra 3-4 contracts that they shouldn't have been able to.
They do seem to have lucked out by drafting and developing a legit super elite goalie though. That is tough to match. He might be the only one in the entire league right now. Though with goalies being voodoo, that could change for them on a dime, too.
