Great observation and I think it's a failure of our scouts, drafting, whatever we do when evaluating players. It's as if we look at specific roles as opposed to multiple roles a guy can fill.
As an example, other than Granlund, name a forward that plays ES, PP and SH? Now think of Granlund in either of these phases of the game and while he's a good to very good player, he's not exceptional at any of them. His compete level is one of the best on the team but from a results perspective, the numbers just aren't there.
Let's look at Boston for a moment. Bergeron and Marchand. Both can play all three phases. I'd say they are great to exceptional in all three phases.
Back to us for a moment, in our history, have we ever had a player like that? I'd say Sully was as close to that as we ever had. I wouldn't put him on their level but he was stellar.
Why do we not draft, develop, sign, trade for guys that are 3 tier players for a lack of better term? We seem to have our 4 lines that we love to equally roll. We have guys that play ES/PP or ES/SH and only Granlund doing all three. I want my best guys on the ice in all phases of the game. I want them getting big minutes. We don't have guys putting up big numbers year in and year out because no is getting more than 18 a night. Give them an additional 2 minutes a night and you'll see better production.
