There have only ever been two successful offer sheets in NHL history where the team receiving the offer decided not to match. Those were Dustin Penner, who came to Edmonton from Anaheim, and
Jesperi Kotkaniemi who went from Montreal to Carolina. It appears that the Oilers are going to have a very hard time matching these offer sheets as they are currently over the salary cap, so these two players will likely end up with the Blues by the end of the week.
