McAvoy is a right shot, making it logical to assume the Bruins will want a right shot to take his spot. They could, of course, ask a guy to play on his off side as well.
So...what are the options?
Kampfer is probably the most likely plug-in here. He’s fairly mobile, is a right shot, and is a bit more offensively inclined than some of the other options, which could help in the McAvoy spot.
