People also forget that Mantha was a couple posts away from scoring 4 goals in 10 games instead of 2. The scoreboard doesn't show everything. The kid made things happen while he was on the ice. It is insane to think playing him with a couple vets in protected minutes and on the powerplay isn't of more value to the team than the 5 minutes Andersson will get to play on the fourth line.
Hell, I could stomach Mantha being sent down if it was Jurco getting the fourth line minutes instead.
