As for Edmundson's (will be 25 starting next season, coming off a 17 point season in 69 games) next contract, let's look at some comparables who recently signed extensions either this season or after last season:
Nutivaara: 23 years old, had 23 points in 61 games --> 4 years, $2.7 mil cap hit
McNabb: 27 years old, had 24 points a few years ago, coming off a 15 point season --> 4 years, $2.5 mil, all UFA years
Gudbranson: 26 years old, career high is only 13 points --> 3 years, $4 mil, all UFA years
Matheson: 24 years old, signed coming off a 17 point season, had 27 points last year --> 8 years, $4.875 mil, 4 UFA years (I think)
Manson: 26 years old, signed coming off a 17 point season, had 37 points this past season --> 4 years, $4.1 mil, 3 UFA years
Severson: 23 years old, signed coming off a 31 point season, had 24 points this past season --> 6 years, $4.166 mil, 2 UFA years (I think)
Pesce: 23 years old, signed coming off a 20 point season, had 19 points last year in 65 games --> 6 years, $4.025 mil, 2 UFA years (I think)
Dumoulin: 26 years old, signed coming off a 15 point season in 70 games, had 18 points last year --> 6 years, $4.1 mil, 4 UFA years
Slavin: 24 years old, signed coming off a 34 point season, had 30 points this past season --> 7 years, $5.3 mil, 4 UFA years
Based on these comparables (and I realize this is only measuring offensive production and similar age), I think Matheson, Manson, Pesce, and Dumoulin represent the closest comparisons for offensive ability, and their contracts ranged from $4.875 mil for 8 years to $4.1 mil for 4 years to $4.025 mil for 6 years, to $4.1 mil for 6 years. Nutivaara is the outlier, as he signed this deal near the end of the season and he only has a $2.7 mil cap hit...but, these are all RFA years.
Thus, I think a 6-8 year deal for Edmundson should be in the range of $4 mil to $4.9 mil. I honestly didn't think Edmundson should get more than $4 mil/year on a long-term deal, but the comparables speak for themselves, and Edmundson's agent will surely be pointing to them. DA will point to Nutivaara and McNabb...we'll see.
