Dan Milstein is an agent for NHL players and the CEO of the Gold Star Family of Companies, which includes Gold Star Sports Management. He is also a breaker of news. Earlier this evening, he went to Twitter to state that Yegor Sharangovich has signed an entry level contract (ELC) with the New Jersey Devils.
That is indeed Yegor Sharangovich. He is indeed wearing a Devils hoodie with a hat nearby. The papers do appear to be contract papers. Milstein and his agency is most definitely legitimate - and quite busy as Gold Star represents Nikita Kucherov (who got paid not that long ago) and Artemi Panarin (who may or may not be negotiating with Columbus) among other players.
