We have the tiebreaker over the Islanders we tie them in ROW. We are 2-0-1 against them this year, and both our wins were regulation wins. Since it's not an equal number of home games between the two, we don't count Ottawa's home game against them. They got two points against us, and we got three against them.
2-0 vs Caps this season. Both at home though. I may be mistaken, but Sens don't have much success in Washington.
Was meaning vs the Islanders since we can catch them in ROW.
As mentioned we have the tie-breaker on head to head. Also checked and we have the tie-breaker against the Rangers as well if tied in ROW and if it came down to it then, and I believe we have the tie break in case of a three way tie as well as we get to drop our SOL against the Isles... so that gives us a perfect point % of available games - while the Rangers have most of the points between them and the Islanders (so overall point % is split between the two).
