Saw this line at The Greek.

For the game Blue Jackets under 2 1/2 goals

Blackhawk defense is stout giving up the 2nd fewest in the NHL

B.J.'s scored 2 or less in last 3

Not to mention Chicago shut out the B.J.'s 3-0, 2 nights ago

Fun fact:
Dec 20 and Dec 23 Black Hawks zipped Detroit 3-0 in back to back
Now have a back to back with CBJ, won the first 3-0
