Bo Horvat, immediately after the Islanders were thoroughly outclassed by the Sabres, 7-1, at UBS Arena on Monday night, used the words “embarrassed,” “unacceptable,” and “inexcusable” to describe both he and his team’s collective mindset and the way they played.

Kyle Palmieri scored the lone goal for the Islanders (13-15-7). Ilya Sorokin made 18 saves. Malenstyn deflected a Jacob Bryson point shot from the low slot past Sorokin’s blocker to give the Sabres a 1-0 lead at 2:07 of the first period.
