Agree that the -1.5 is not worth the nominal gain in price. However, given that the wind is out and the total is high, runs are cheap, in spite of the starting pitchers in this one.
Cousins is very home friendly, at 18-8. If I had to, I'd play the Cubs on the RL at about -170, but that's a lot of juice. Better play is the over 10.5. Wind is out at 10, and the Cubs like hitting lefties.
