Calvin de Haan
Calvin de Haan is not the problem on the blue line, but he is one of the only guys outside of Erik Gustafsson to not have a contract next season. de Haan is a great veteran player for this team, and he can be that for any handful of teams this season towards the deadline.
If the Blackhawks remain outside of the playoff picture, de Haan is a great candidate to get traded seeing as he is on the final year of his deal and blocking players like Wyatt Kalynuk, Ian Mitchell, and Caleb Jones from taking bigger roles on this team – granted Kalynuk and Jones are not healthy right now.
The only real reason the Hawks choose not to trade de Haan is to treat him as the rental player this team needs on the back end come closer to the playoffs, but if they are out of it and do not intend on re-signing him then they will probably want to make a move.
With Seth Jones, Connor Murphy, and Jake McCabe making the most money on the blue line over the next handful of years, it makes sense to leave the other spots open for someone of the younger options this team has in their system.
A return on a de Haan trade would be interesting to see, he definitely could score a second-round pick or better depending on the market and how much the Hawks are willing to hold back.
