Aside from being homegrown, I think the real parallel between Dubinsky and Miller is/was their attitude when they were early in their career. Cockiness can be a blessing, but it's a detriment when the attitude gets in the way of the play. Dubinsky really matured during his time in Columbus, and I've seen great improvements in Miller's mental game because he definitely has the talent.
In regard to style of play, I don't see as much of a similarity. They both play the boards well [Dubinsky being superior in that regard], but they accomplish this by different methods. Dubinsky protects the puck whereas Miller crushes the skater for turn overs with his checks. Speaking of which, although Miller is not a tower of a player, this guy his like a ****ing truck when he gets someone lined up.
Anyway, I like what I've seen over the last half season in Miller's play, and it will only help us going forward after the most likely semi-house clean this summer.
