Dunno if you're aware, best goalie prospect in hockey is currently playing in Russia and will be 23 in August. Reports out of Russia said he didn't want to sign with the Islanders while Garth Snow is in charge.
Now Lou is running the show, Stanley Cup winning Trotz is the head coach, Tavares is rumored to be sticking around, and there just so happens to be big hole in net. Trotz's defensive system is great for goalies, perfect opportunity for a Russian wunderkind prospect to take over the starting role immediately to justify a nice juicy extension during RFA negotiations.
You trade a high 1st for Grabauer and sign him long term to starter money? That opportunity goes bye-bye. This is a critical time for the Sorokin camp to let Lou know their intentions to take the starting job, or allow an outsider to come in and usurp the throne.
