Clarity is the word that people close to John Tavares have been using going on seven months now, ever since the Islanders’ captain informed Garth Snow and team ownership that he would be waiting on contract talks. There may be some clarity coming soon on one of Tavares’ key issues. New York State may be nearing an announcement on the winning proposal to develop the parcel of land at Belmont Park, according to several league sources, possibly before the calendar flips to 2018. The Islanders’ main priority is to start building their new arena as soon as possible if their proposal is selected. Their close-second priority is getting Tavares signed to a long-term contract. Islanders co-owner Scott Malkin visited last week with Pat Brisson, Tavares’ agent, in Los Angeles. Malkin and Brisson have kept in constant contact since last season, when the Islanders turned their focus to a new arena. There’s no indication that Tavares would change course and decide he’s ready to sign if the Isles win the Belmont bid. He declined to discuss anything to do with a possible arena decision, which is not official. But this would be the first big step for Tavares toward getting clarity on one of the main holdups for a new Islanders deal.
