Maybe I'm wrong on this but back in the day the NHL gave teams options - play a lot of premium games on weekends and get more back to backs or less weekend games with fewer back to backs.
I did not count them but looks like a lot of home Friday and Saturday games. So I'm assuming the CBJ opted for that. It makes sense attendance wise, walk-ups for weekday games was usually much less (it appeared) than weekend games.
But that is my guess is the CBJ opted this year to take more Friday-Saturday home games, which leads to more back-to-back games.
EDIT: 19/41 home games are Friday or Saturday games.
