The Colorado Avalanche big line has stayed together till recently. Personally I would like to see them get split up, but differently then what coach Jared Bednar decided to do. I personally would like to see either Nathan MacKinnon or Gabriel Landeskog moved down to the second line instead of Mikko Rantanen. I have a few reasons for preferring those two as well.
If MacKinnon was moved we could swap centers and have J.T. Compher move to line one with Rantanen and Landeskog. Compher would fit in on this line because he has great vision on the ice and would not look lost.
