First of all, I haven't stopped smiling since I heard the news! I'm so glad he's signed and can't wait for the season to start!
As for the lines, Therrien will definitely split them up and make 2 lines, probably like this:
Recchi-Crosby-Armstrong
Ekman-Malkin-Malone
OR
Ekman-Crosby-Armstrong
LeClair-Malkin-Recchi
Either setup would be fine with me...
