Kampf is easily worth his contract. Joseph also has 19 pts in 26 games.

Not sure why Chabot is there.

I can understand your other ones although I disagree with Parayko and Koktkaniemi. I wouldn't put Dubois in the Anchor spot (YET).

2.4x4 for a 4C that provides little to no offense and has been bad defensively this year is not worth his contract

Jesperi is going through a rough patch but usually produces very well when given enough ice time. He has been routinely stuck on a line with a guy who is a black hole in his own end (Necas) which is why his own analytical numbers are so rough in his own end. Also has regularly had no PP TOI

Kampf is a solid bottom 6 guy. He is slotted as a #4C because he has limited offence. But he is historically really strong defensively, has a very high compete level and he plays more than a 4th liner because he gets number one penalty kill duties. A good #4C is more valuable than 3rd line wingers.
