The Boston Bruins have up against it so far during the NHL training camp. 

Even with some key members missing, head coach Bruce Cassidy has to push on as if they might not be back. 

Those key members of course being David Pastrnak and Ondrej Kase. 

On Thursday, Cassidy revealed his new power play units without those two around. 

PP1: Krug, Krejci, Bergeron, Marchand, DeBrusk
PP2: Grzelcyk, McAvoy, Coyle, Studnicka, Bjork

The second unit definitely looks a little thin right now. 

What do you think of Cassidy's new PP units?
