Mirtle's post on Morrison's signing in Anaheim brings up the Ducks' cap situation. You can see their payroll here. James mentions the often heard rumour of Schneider's departure.
Ottawa could fit Schneider's salary under the cap with Vermette at 3 and Mezsaros at 3.5. It would be very tight and you'd likely see some salary moved somehow.
