This question is almost too tough to answer as I'm happy which each and every new and re-signing for different reasons as each seems to have taken to their role in the team brilliantly.
On the forwards side as others have already said, Joey Martin is the stand out for me with incredible work rate, forechecking, backchecking and a great chemistry already with Lord and Morrisette producing excellent numbers. Mychan and Clarkson have been impressive but with different roles in the team so not necessarily shown on the points front. Very pleased with Haddad too, who is big strong and scores some great goals. Walton and Culligan have shown flashes of what they are capable of and I'm sure when they find the right line there is more to come from them.
Of the D men I have been most impressed with Hendrix. I was expecting a tough guy who was maybe a bit less skilful than the other D men but this guy is a lot more than that. He can hit, fight, make great plays and score goals. Also very pleased with Hotham and Hudson who are both very smooth skaters and comfortable on the puck but can mix it when necessary too and not afraid of anyone. Just love how nasty our D can be with 5 big guys on it.
So overall I'd go with Martin just shading it ahead of Hendrix, then Hotham, Haddad and the rest! So all of them!!!!!!
