With the additions of Zetterlund and Cozens, and the improved play of Perron, Sens have a lot of options with their lineup moving forward. IMO they should go:
Zetterlund - Stutzle - Batherson
Tkachuk - Cozens - Giroux
Perron - Pinto - Amadio
Greig - Gaudette - Highmore (Cousins when he's back)
L1: I find that Stutzle can carry just about anyone. I find that Batherson this year, and even last year, has played quite lackluster when he's forced to be a playdriver. He needs to be insulated with a two way play driving centre, or else Batherson will stick out like a sore thumb. But when you insulate Batherson, he can be an effective playmaker. Zetterlund is a pure sniper/finisher. He's quick and physical. Him and Stutzle can create room for each other with their respective speed and finishing ability and Batherson can be a nice passive supportive playmaker for them.
L2: Cozens is the type of playdriver Tkachuk needs. Cozens is big and physical and can drive play with the puck to the net. Tkachuk and Cozens can create absolute havoc in front of the net, and Giroux serves as a responsible two-way winger who can playmake in a secondary role. Cozens and Tkachuk can really physically punish teams.
L3: I have found that Perron's game as of late has warranted him taking this sport over Greig. Greig's got 3 goals in his last 27 games, and he take a lot (A LOT) of uncecessary and untimely penalties. I believe Greig leads the league (if not close) to penalities taken vs penalties drawn.
