Why is arguing Konopka's PIMs a relevant point? Konopka spent 3.5 (per ten mins of ice time) defending his teammates, something Miller did not do this season. Since most of his PIMs are from fighting (or 10 min misconducts from the refs 'settling the game down'), I can't agree with your negative spin on the stat.
Well Drew Miller put up almost as many points in 66 as Konopka has in 195, so I would say that right there would put him as more valuable, he kills PKs, he goes to the dirty areas, and best yet, he doesn't average over 3.5 (per ten mins of ice time) minutes in the penalty box per game. Konopka isn't particularly defensively sound (not compared to your average Detroit center), at least not from what I have seen from his stats and the games Ive seen him in.
If you think a guy who spends over 1/3 of his ice time per game in the box is a good addition to a team thats your right, I personally think its a poor idea. As I keep saying if we can get a player that can add grit and actual scoring talent to our team I would be in favor, but no warm bodies who are only on a team because they can fight.
The best option for any grit would come on the blue line as a 6th/7th defenseman, with the high number of offensively sound D men Detroit has adding some girt on the back end wouldn't hurt.
The player you want won't exist on the Wings. There are only a few scorers who will fight (Lucic, Clowe, Stewart), and they come at a price premium. Also, these players would be encouraged by the Wings not to fight since they would be key offensive figures. If you think Konopka is bad in the box, try having one of your second liner's in the box that much. The argument for a skilled fighter contradicts your first point of too many PIMS because of the necessity of PIMs to fighting.
Konopka got 9 points this year playing with Trevor Gillies and Michael Haley (or Matt Martin). Think for a minute about those players and compare them to Helm and Eaves. Then think more about the significant amount of offense Miller adds above Konopka- it's not nearly as much as you think.
