Who cares; he has to earn a contract for next year, make him work! And funny enough; that's the role he was traded here for!
And check your thinking, has he outplayed Danny, Raymond or Burrows? Not this year, and he's not as fast as Raymond, nor as big as Booth who can each put up similar numbers. And when he does score it's usually only with top players. That means he is not who drives the offence. Add it up and he's a depth guy who can play top 6 when asked. But if Higgins is on our 4th line, we're also in a very good place!
Look, he has a great motor. Even if he's "4th" line, AV trusts him and pops him over the boards every time someone is puff'd after a PK, or Raymond is being mis-matched. He'll still get way more minutes than the average 4th line guy!
As to the OP's question > Ebbett!
I don't think Higgins would be okay playing on the fourth line.
