I'm not really sure what type of guy you mean? Do you have any examples of someone you think fits the bill in terms of style of play? Doesn't have to be someone on the market, I just want to get an idea of what you're looking for.
I always wanted to have an Erskine type player here. A guy who regularly dressed on defense for the Capitals, and was an enforcer to boot. Sheldon Brookbank is another such player.
These types of bottom pairing D-men clear the crease, stick up for teammates, and are tough to play against in a playoff series. And they're bone-fide tough guys/enforcers. Also, these kinds of players don't cost a lot of money.
Now Helm and Tatar are "better" than Franzen too. Is someone playing a practical joke on me? Am I being punked?
It's pretty obvious they they work harder, and if that alone makes them better in your eyes then great, but I hope you realize how seriously flawed that thinking is. For instance, Jiri Hudler was a real hard worker, was he better than Franzen too?
