The Islanders are notorious for playing their fourth line as much as their first line some nights, but as Keefe said, having a bottom-six you can trust to throw on the ice at any point in time is something the Leafs have not had in a long-time. There have been certain players in the bottom-six that Keefe has relied on more, but never really a full line, even dating back to November and December, when Keefe would often dress
Ryan Reaves just to play him for 6 or 7 minutes and then allow some of the team's stars to take on extra shifts on the 4th line.
