Hate to say it, but Ghetto has not been good lately. He needs to produce and he isn't getting much done.
I think he's been fine in a 4th line role. He's winning puck battles and getting the puck into the attacking zone, which is what he does best. He's never gonna be an ace finisher or setup man, it's just not his game. He's also not terribly useful in a bottom-six role. His lack of utility is mainly why Bergevin ended up moving him for a fringe scrub a couple seasons back.
I don't think he's got his speed back either after two consecutive leg injuries. He's this year's Colin Wilson.
