Anisimov, Kruger, Teuvo, TVR, and potentially Pokka are the guys likely to be decided between on who to protect or not. Unless there is someone else they sign they may want to protect suddenly like Panik or a incoming trade/ufa piece this offseason. Maybe if Hartman has a strong year he'd be a questionable target for vegas.
Since anyone who's ELC began this season is exempt they don't have to worry about bunch of younger guys or even Panarin.
