I have to jump in here and give my .02
While I think there are comparisons between Deadmarsh and Brown there are also some major differences.
Deader is a much faster skater than DB. With that said, it explains a lot more the reckless abandon that Deader played with. Brown seems to be smarter and pick his spots when he hits guys. He laid out one of the Pack's guys the other night and was probably skating 30% when he did it.
Because of Deadmarsh's speed, he was able to go around guys and break into the net (at usually bad angles), but get shots off. Brownie tends to put himself 5 feet in front of the net constantly and get rebounds and cause havoc. Deader did this as well, but Brownie I think in the longrun will be more effective.
Size wise, I guess they are close...right now. Brownie just turned 20 and most likely is not done growing. At 6'1" 205lbs, he's already bigger than Deadmarsh, 6'0" 195lbs. I think when all is said and done Brownie could be 215lbs in a few years, and if he works on his skating with the added weight, it will benefit him.
Deadmarsh scored 30 goals once in his career and was a 20 goal scorer numerous times. I think Brown will be a 30 goal scorer in this league more than once primarily because he will benefit in his time with Manchester playing with Cammalleri, Lehoux, Grebeshkov, and Gleason. These are guys that LA management are touting as the next generation. If they stick together, the more they play, the better they will get. The results from this year already, speak for themselves.
I think overall, I can see why there is a comparison. I'm sure if someone pisses Dustin off enough, he'll go with them. However, at this point, I think overall Brownie will bring more to the table scoring wise and hockey smarts, but will be lucky if he can match Deader's intensity and toughness.
It would be nice if the season started up if Deader was healthy enough to sign with LA and be a mentor for Brownie. One can only dream...
