Winning covers up a lot of warts.
Whatever you say about Karlsson within 3 years of being named captain the team was making the playoffs and he had a legendary run where we took the eventual Stanley Cup winner Penguins to 2OT Game 7 in the Eastern Conference Final.
3 years of Tkachuk and no playoffs, not really that close either. In year 4 the team still sucks.
Does it all fall on him? No. But if this team continues to fail to make the playoffs the question needs to be asked about Tkachuk specifically and about the core more broadly. Why can't they even make the playoffs?
The four years Karlsson was our captain we made the playoffs 2 out of those four years. A yoyo of playoffs/no playoffs, its not like we were a perennial playoff team.
Year 1. The only reason we made the playoffs was a magical run by the Hamburgler to sneak in.
Year 2 No playoffs
Year 3 Year was the Conference final run where his play in that playoffs will be remembered in Senators history.
Year 4 No playoffs
I have a feeling based on the stuff Brady is made of he has it in him to carry the team on his back if and when we ever make the playoffs as well, might not be a legendary as Karlsson run as he is only a winger
