My point is Haley or Radil. They lose that game.
If you’re really desperate to pin the game on one player then Braun should be your guy.
That's a non-falsifiable claim to make. You simply don't know how the game changes with that lineup change. Radil certainly doesn't take the penalty that allowed Vegas to take the lead so quickly after tying it up which happened quickly after taking the lead initially. Radil certainly doesn't take Haley's second penalty that killed momentum when they were responding to Vegas taking a 3-2 lead. Radil almost certainly doesn't spend 80-85% of his shifts in the defensive zone.
Let's not pretend like there weren't a lot of momentum swings in that first period and two of them were Haley doing something stupid setting the team back big time. Haley is a big reason why the team as a whole didn't respond appropriately to those swings.
