Miller more physical and while it ain`t sexy, I`ll try and lay out my reasoning for why CJ and his staff would prefer Miller in over Morrow. For one, yes, Morrow can break the puck out quicker, hardly an argument there however, unless he has time, rarily do I see Morrow`s feet getting he and his teammates out of trouble. Far too often he`ll take that puck and fire it around the boards without so much of a look to see what`s out there (now, to be fair, there isn`t a D-man out there who hasn`t done this but..)
Whereas with Miller, I have seen him on numerous occasions eating the puck, hugging the boards with the puck rather than try and force it through bodies or hammering it around the boards. Miller and Quaider, for the most part, don`t exactly throw out the welcome mat to opponents to come and camp in front of the net, Morrow and C Miller, bring little to sway opponents
Now, I`m on the record that I go with mobility 8 days a week and would welcome both of C Miller and Morrow in the lineup game in and out. That said, I know with those two in there, mistakes will happen, and the odds are, IMO, those mistakes will end up in the back of the net too often.
Pro coaches don`t coach for the future, it`s not their job, their job is to win now, and CJ is no different, potentially more risk averse than other coaches but I would hazard a guess that if we had a panel of all NHL coaches and presented them a scenario where you have a vet and a kid/younger prospect available and you have a spot to fill, on a team literally fighting for their playoff lives game in and out, they would all play the vet unless it`s a team like the Leafs who are going young, warts and all
