His most recent fight against Calgary was purposeful, they were running around despite having a big lead, so Boll took a big run at someone and then dropped the gloves with Engelland.
Otherwise I'd agree that he's been fairly useless. I believe we already have enough scrappy players who can stand up for their teammates.
The revenge fight against Nolan in the second LA game (for sucker punching Getzlaf in game 1) and the Lucic fight were also doing his job. The others have been pointless fights.
Let's look a little more critically
11/1 vs Clifford
Boll 59.2%
Draw 39.2%
Clifford 5.6%
I'm all for Clifford getting beaten at every opportunity, probably the only time this year he's looked like a legitimate fighter.
11/2 vs Sestito
Draw 48.8%
Sestito 40.5%
Boll 10.7%
A prime example of how an enforcer is supposed to do his job. Unfortunately, that guy's name was Sestito.
11/6 vs Engalland
Draw 49.3%
Engalland 43.5%
Boll 7.2%
Pointless, staged fight that a mix of hugging and getting his face repeatedly punched.
11/12 vs Bass
Draw 64.1%
Boll 28.2%
Bass 7.7%
Fights the wrong guy, and...yawn.
11/20 vs Nolan
Nolan 62.7%
Draw 21.6%
Boll 15.7%
Tries to do his job, but actually sends the message that a cheap-shot to our captain carries no real penalties when he gets his ass handed to him.
12/3 vs Lucic
Boll 57.1%
Draw 28.6%
Lucic 14.3%
Hands down his best work of the year getting a top line guy off the ice, but pretty yawn inducing as an actual fight.
12/3 vs Engalland
Boll 46.2%
Draw 38.5%
Engalland 15.4%
Doing his job laying a return cheap shot, but the only part of the fight he wins is punching a guy who's laying on the ice.

It's simply not an impressive body of work. He's usually the very distant 3rd choice in his "draws", and his wins are squeaked out with one exception. This is not the stuff that legendary enforcers are made of. It's not even the stuff that competent 4th line goons are made of.
