Ellis also has a theory as to why he and Josi have worked so well together.
"[Josi] loves to have the puck and skate the puck, so for me it's more or less get it to him, let him do his thing and get open again," Ellis said. "He has such great vision and he is a great passer, a great sharer of the puck, so if you're open and available he'll find you. For me, it's get open for my shot, use that as much as I can."
That Ellis has made it work with Josi has allowed Laviolette to preserve the pairing of Subban and Ekholm, which is big considering they've been excellent too.
Subban and Ekholm are Nashville's top two defensemen in shot-attempts percentage (SAT) overall (55.35 and 53.82) and in close games (55.03, 53.49) even though each has started more shifts in the defensive zone than in the offensive zone.
"There have been lots of questions this year about why Roman and P.K. aren't playing together," Laviolette said. "It's because P.K. and [Ekholm] have some of the best analytical numbers in the business and they're two big horses that can take down big guys.
"We've really liked the pairings."
