I still haven't seen an official list on departing Oilers RFA's anywhere, but Guy Flaming has a post up tonight with most of the details which is almost certainly accurate. It's actually a recap of his excellent (and lengthy) post from last week which I somehow missed and the whole thing is worth a read to anyone who follows Springfield.
The players of interest here are three defensemen (Mathieu Roy, Sebastien Bisaillon, Josef Hrabal) and forward Tyler Spurgeon (pictured above with Stephane Goulet, who was also let go) - decisions which are at least a little bit surprising.
