Well straight value i dont think its that far off.
Kuznetsov vs Monahan points last 5 years
16-17; 59-58
17-18; 83-64
18-19; 72-82
19-20; 52-48
20-21; 13-20
Last five years totals;
Kuznetsov 89+190=279 in 321 gp = 0,87 ppg
Monahan 121+151=272 in 334 gp = 0,81 ppg
Mohanan is 2 years older. Has almost 1,5m less of cap hit.
Monahan has this + 2 years on term, Kuzy has this + 4 years.
Actual money owed for Monahan the next 2+this years about 13,375 millions.
Actual money owed for Kuzy the next 2+this years about 14,5 millions + 16 millions for the next 2 years.
So while Kuzy is little more effective in total points, Monahan scores more goals. While Kuzy is 2 years younger, Monahan has less cap and money owed.
I think its fair deal on value point, but Kuzys higher ceiling makes it a no go for Caps at the end. If he goes on the cup-run-mode he had 2018 he can be the difference maker in first round exit vs winning a cup.
