Senators coach Paul MacLean wanted a bigger body around the opposing net -- something the 6-foot-2, 188-pound Stone can provide. Due to his previous experience with Spezza, Stone is expected to flank the veteran center on the right, with Milan Michalek skating on the left. The move has made Cory Conacher the odd-man out. Stone had 38 points in 54 games in the AHL this season.
