Both goaltenders are set to be free agents in the summer, with Kahkonen's $1 million cap hit a little higher than the $975k for Driedger, with very little implications of that for both teams moving forward with 24 hours left at the trade deadline.
In a few months, this could be a potential Stanley Cup Finals matchup between two of the NHL's best teams, and if that ultimately happens, it's very unlikely that either player in this deal will be playing a significant role for either team.
Ultimately, we've already seen some very surprising deals made at the deadline, but this one may be the most surprising of all given that it has very little impact on either team, but perhaps this is leading to something more. As always at this time of year, only time will tell at the NHL trade deadline.
