I believe, with Florida's just-completed regulation victory over Buffalo, that the Caps have been mathematically eliminated from playoff contention. There are now 8 teams in the conference with 87 or more standings points and 38 or more regulation/overtime wins. If the Caps were to win their 5 remaining games in regulation or overtime they could accumulate 87 standings points, but only 37 regulation/overtime wins, which is the first pertinent tiebreaker.
Now it's just a matter of where they finish in the standings.
