Seems right now they're either somewhat rotating them, or playing the one whose playing better. Emery just got back from offseason surgery and has only played 2 games, however his last game he let in 4 goals in the last 10 minutes of a 5-0 lead over Atlanta so I think Paddock's not too impressed with him or feels he's still a little rusty and is playing Gerber for abit as he's playing great.
Not sure who will be in net Tuesday vs the Leafs!!
Ultimately at the trade deadline or offseason at the latest, the Sens have to trade one of their goalies (unless Emery is bad, it'll still probably be Gerber as he's older) as they'll only have about 10-12 million to sign 10 players, freeing up the 3.5+ million from one of these guys is a necessity, granted all the players they need to sign are in the 0.8-2.0 million range. (Except Redden who is gone at seasons end)
