Bergy just isn't completing his plays. He puts in effort and does a lot of just "throw it toward the net". Usually he perfectly compliments the snarl of Marchand and he gives him some nice setups, but he seems to playing an ultra simplified game where he's not looking for a crisp pass, but just a bounce of some sort.
It's obviously tough without a first line caliber player to play with (in Pastrnak's spot), but it's something I've been noticing even with Pasta present. It's our only line that is purely skill based. Am definitely looking for a little bit more out of Bergeron.... Whoa, that was a weird thing to write.
