I would add Appleton too, although he might just barely be worth considering. I have really liked Apples though. Consider the opportunity he has had when measuring his achievements. If Rosie doesn't make it at 2C then I think he and Apples are near even.
Then there is Lemieux. May also be close to the cut off line. Not quite as skilled as the others but as long as he continues to control his worst impulses the grit he brings is valuable. I'm not anxious to include him either.
All I could see adding would be a little more quantity.
I wonder if Ottawa has interest in one of our 4 underrated dmen? Kovacevik, Gawake, Vallati or Chisholm?
