Serge has a lot of talent to go along with his blunders. I wonder if his problems this year have been with the new defensive system as the whole team struggled for the entire first half of the season. Serge isn't the only one, Perbix looks like a different guy this year.
Of Serge, Cirelli, and Cernak, Serge is the one with the most potential to live up to his contract in my opinion (because Cirelli lacks the offensive talent and Cernak's health issues). He took a step forward last year before this year's defensive scheme got Blashill'd. I'm not for trading him. though part of that might be cause I haven't watched him try to make a play with the puck on his backhand in our zone lately
