I think Hanifin+ for Rielly could be something worth exploring. Hanifin has not lived up to his #1 potential at this point, but he has 3 years left at practically the same cap hit as what Rielly has right now and is a solid 2nd pairing defenseman. At 24, he may still be able to improve and at least become a Muzzin-quality defender here... But with more offensive upside.
It's a downgrade, because Rielly is a #1 defenseman and Hanifin is a #3 at best right now, but if Calgary gives us a 1st round pick in there too... Then it could be worth our time. Calgary lost Giordano and could use a guy like Rielly to lead their defense on the left side, especially in the offensive end. We are not in the same division nor conference, so that is also not a major concern. Seems like a good fit overall.
