Bednar has done a good job letting his best players go a bit and be more creative. That said, how much of this is MacK and the first line just beasting it? MacK has a part in 38% of the Avs' goals with points, and I'm sure that percentage is higher when you look at other impacts... probably to the tune of 42-44%. Bednar should get some credit for MacK turning the corner, but I think players like MacK can elevate beyond any system they play in. It took a bit longer for it to click for him, but it obviously has. If MacK was operating at a ~55 point pace instead of his ~100 point pace... the Avs would have ~20 less goals on the season to this point. That would put them in the mid 20s. If you look past the 1st line, the forward production is still pretty mediocre. Only Kerfoot and Soda are on pace for more than 40 point seasons. Soda's should be higher as his play is at a better level than that, but Nieto is letting that down. Kerfoot is slowing a bit, but should still crest 50. There are a number of forwards in the 30-40 point range (Ghetto, Comeau, Nieto, Compher, and Yakupov), but I'd only expect Comeau and Ghetto to crest it for the season (Compher has too many injuries).
The Avs forwards have collected 105 goals on the season. Landy, Mack, and Rants have 44 of those goals. Duchene has 4. The other 14 forwards on the team combine for 57 goals. The team is very top heavy right now, and with the way MacK is playing... the Avs can afford that for now, but at some point, Bednar will have to get some scoring down the lineup.
