The sens play 4 games at home including games against Chicago and Philly. Also carolina will be locked into a spot on the road in the last game of the season. Montreal is 3 points back and the sens have the tie breaker. They would have to run the table and Ottawa would have to only get 4 points. Not very likely.
And if this improbable series of events does happen I'd rather play Washington than Tampa. So it doesn't really matter.
Yup, to heck with running the batteries low to defend a WC1 slot. Rested and healthy, as much as possible, is better.
