If the Caps need an enforcer, who can it be?

Here, we (Collectively) often talk about the need for an enforcer, or more grit.  We discuss whether or not the aspect of an enforcer is necessary in today's game, among other things.  We also get into the discussions of how this player isn't acceptable (John Erskine isn't good enough, Donald Brashear fights teenagers, Matt Cooke knees people, etc).

The problem with this mindset is that most gritty guys or enforcers have done some dirty crap.  Grit and dirt in the NHL are separated by such a thin line that it's often crossed, and often unintentionally.

There are some players who can contribute solidly to the physical game and score, like Jarome Iginla.  The only problem is, those players who can do that aren't going to move.

Who, then, should the Caps use to add this element that the team seems to be missing(outside of Matt Bradley)?

We all love Matt Bradley, but his paper-thin-skin keeps him from really being effective against guys like Koci.  He's perfect for his role - 4RW.  Benching him for an enforcer would obviously be a mistake.

Erskine is the next choice, obviously, since he is already on the team, but it's clear that the guy is a 7D.  He is slow on his feet, and often makes poor puck decisions.  In an ideal world, he's riding pine unless we're playing the Flyers or the Hurricanes (or now, the Avalanche, I guess).  1.25 million is a lot to have on a guy who rides pine, but he's not the worst d-man in the league, and he does what he can, even though what he's asked right now is beyond his skill set.

Sugden is out, due to his jump to the KHL.

Oscar Osala seems to rack up penalties in Hershey, while still providing on the offensive end of the ice.  I've only seen him play once, but he seemed to have some fire.

Pinner in Hershey seemed to have that element as well.

Della Rovere seems to be what everyone wants.  The only issue with that is time.

Or do we not wait, and do we look outside the organization?  Do we have enough internal grit already that we don't have to look externally?  It's a tough argument.
