Jaroslav Halak started between the pipes for the second game in a row Monday, marking just the second time this year an Islanders goalie has made consecutive starts. Despite giving up a pair of first-period goals — a short-hander on a bad line change and a power-play strike — the netminder rewarded coach Doug Weight for his decision. Halak limited further damage by the aggressive Golden Knights and kept his teammates in it early before they came alive in the offensive zone for a 6-3 win at Barclays Center. Thomas Greiss (five starts) has yet to start in back-to-back games for the Islanders while Monday was the second time Halak, who finished with 31 saves in his seventh start, got the opportunity. “[Halak’s] numbers and the way he’s played, he’s probably outplayed Thomas to this point in those games,” Weight said. “We were thinking of two days off before we play Washington [on Thursday]. Just decided to talk with [goaltending coach Fred Brathwaite] for a while and decided to do it.” While Weight is riding the hot hand, it doesn’t mean he’s settled on a true No. 1 goalie.
