I mean.... a bottom six D? There are only six D... so a bottom six, would be the same as the top six.
Seriously though, Niemela is better than I thought, after watching him the last few games. I really like how he closes down on the opposition, and smothers them, as they enter the zone. That being said, how much of what he brings to the table, do you need, or should you have in the lineup? Hopefully Lilly continues to grow, and with Rielly and Lilly in the lineup, I'd argue you don't want Niemela, unless he becomes better than either of those two, which is to me unlikely.
I'd move Niemela in a package that brings in a guy who can play with Mo, on a contract that has term, and allows us to continue to build the backend up.
No arguments on the others really.. but if Cowan and Minten work out, as well as the Russian, I think we are in ok for a few years, and have time to rebuild the prospect pool. That is, as long as we don't move out some of the guys we have now.
