They can't call Steve Eminger up, he's on an AHL-only contract. Ditto for Frankie Simonelli. They aren't going to waste a contract and cap space on either of those two. Breen and Cross I guess are possibilities but that's over thinking it. I don't see why it won't be Trotman. He's serviceable and it's not like Miller/Morrow/Bartkowski are anchors in the lineup that can't watch a game or two here and there in the press box if they get too worried that Trotman has sat too much. Or he rides the shuttle up and down 95.
Edit: Back to McQuaid, out of the 10 D the Bruins have dressed this year, McQuaid is 9th in CorsiRel (-9.0 per 60 min) only ahead of Joe Morrow. Those two have been paired together for the majority of Morrow's time in Boston, so It'll be interesting to see how Morrow's game goes without McQuaid. Who has been the true anchor on that pairing?
