As an Islanders fan, I'm curious as to where you heard that Somerby wants to head to UFA in Mid August. Not disagreeing with you, just haven't heard that from what Somerby has said in the in the past about his relationship with the Isles.
I can never imbed tweets properly, but here;
"@JonathanSigal
Doyle Somerby, @TerrierHockey's captain, will wait until Aug. 15 to pursue his options, per source. He was drafted by NY Islanders in 2012."
Sigal ran the Boston Hockey Blog this year, which covers the BU men's hockey team for BU's student newspaper, so he's pretty credible. Also does a lot of writing for the New England Hockey Journal.
