Rangers played 6 preseason games. Allen played in 3. Against the Flyers, Oilers and Kings. He paired with Staal against the Oilers so I'm sure he got his share of ice time in that one. The pairs against the Kings were Moore/Stralman, Del Zotto/Bickel, Falk/Allen. Allen played the right side pretty much if I remember right throughout training camp and in those games. The Flyers had the likes of LeCavalier, Simmonds, Hartnell, Voracek and Coutourier in their lineup. The Oilers had the likes of Schultz, Hall, Hemsky, Eberle, and Perron in their lineup. The Kings pretty much had their full lineup with the exception of Justin Brown.
What I remember of Allen is he played very well. His positioning was good. He was calm with the puck--not a panicky type. Moved the puck well. His size is fine. Average physicality. He's had a good rookie year in Hartford.
More obvious that this call up is insurance in case Stralman and Staal can't go on Sunday than it means DZ is being traded--though DZ might be on the way out--Allen's coming up is to fill holes. With McIlrath out short term and I believe Bickel is out as well--the other options would have been Aaron Johnson who has extensive NHL experience but who is a left sider or Danny Syvret.
