I'm more concerned about our blue line than anything else. It is comprised mostly of younger players, and we have some guys coming on that should be NHLers in the next several years.
I think at this point you can say that Kronwall, Ericsson, and DeKeyser are our 3 most reliable d-men. Smith has been a bit of a mystery for us, showing a lot of skill and nastiness at times, and then making dumbdumb decisions at others. Kindl has been fairly disappointing to this point. I think he has peaked under Babcock as a 3rd pair ES kinda guy and 2nd PP unit player, who could play more in case of injury, etc. But he, much like Hudler, Filppula, and others, will never be his best under Babcock. Quincey hopefully walks this summer in FA.
I think at some point you have to make a move for an established RH D. It is a glaring hole on our team. It makes breakouts and defending less conventional at times, and in the past has made us use players of Samuelsson's ilk on the power play. Unloading Smith and/ or Kindl + Almqvist (another guy I don't see hacking it by Babcock's standards) + whatever other piece may be asked for a guy like Girardi, or someone similar, may not be a bad move. I'm trying to imagine our team in 2-3 years time.
Something like...
Kronwall - Girardi/ other RH acquisition
DeKeyser - Sproul
Ericsson - Marchenko
Ouellet
guys like Kronwall, Girardi, DeKeyser, Ericsson can PK. Kronwall + Sproul could be our 1st PP pair, with any of the other 4 being more than capable of playing on the 2nd pair (some better than others) + use of forwards on points is still an option.
The only real blow would be losing Smith, but if he could bring in something we don't have on our team/ in the system, I think you have to take a long look at that move. Smith doesn't necessarily do anything that guys like Kronwall, Ericsson, Ouellet, DeKeyser, even Kindl for now as a LH D don't/ can't do. If Smith was RH I would cling to him for dear life as he helps hold the offensive zone cycle and offers a different option on break outs, but he is redundant as a left handed shot. While having an even split of LH and RH isn't essential, it definitely helps coaches match lines and creates a little extra time and space in certain situations.
