New York Islanders Predicting RFA Contract Extensions

At the end of the season, the New York Islanders will have three notable restricted free agents to get under contract. How much money and term should they commit to their youth?
We’ve already looked at what the New York Islanders might give to some of their pending unrestricted free agents, what about some of their restricted assets? By the end of the 2018-19 season, the New York Islanders will have three (notable) restricted free agents needing new deals.
The three players are Anthony Beauvillier, Michael Dal Colle, and Josh Ho-Sang.
"Note: John Stevens is also an RFA at the end of the season. The undrafted player has three points in six games for the Bridgeport Sound Tigers. There’s no debate that he’ll get a minimum deal if the Islanders keep him."
Those three Islanders RFA have a number of different questions hanging over each one of their careers. Questions with answers that will ultimately determine the dollar amount of their next contract from the New York Islanders.
The last two RFA deals that New York Islanders President and GM Lou Lamoriello will play a large factor in what these three RFAs will get. The contracts that Devon Toews and Ryan Pulock are without a doubt precedent a setter for how Lou views what players should get after their entry-level contracts (ELC).
So how much money and for how long should the New York Islanders offer to Anthony Beauvillier, Michael Dal Colle, and Josh Ho-Sang?
