I think we can get more for Simmonds. I think that someone like Kirill Kaprizov or Sam Steel would be ideal, but I'm not too high on Taylor Raddysh and I would rather give that position to Wade Allison when we are able to sign him.
An ideal Simmonds trade would be something like this:
Wayne Simmonds (50% retained)
Sam Steel
Maxime Comtois
2018 1st round pick ANA (top 20 protected)*
Conditional 2019 3rd round pick (condition being ANA makes it to WCF with Simmonds playing 50% of playoff games)
*if it doesn't convey, ANA sends their 2019 1st round pick and their 2020 2nd round pick
Wayne Simmonds
Rights to Kirill Kaprizov
Rights to Andrei Svetlakov
2018 1st round pick MIN (top 20 protected)*
2020 3rd round pick
*if it doesn't convey, MIN sends their 2019 1st round pick and their 2020 2nd round pick
