I agree, you should be all over Cubs under 88.5.
Other interesting ones:
Yankees under 102.5 (everything would have to break perfectly for them to hit 103)
Astros over 82.5 (could benefit from Cubs' injuries, and still a decent team)
A's over 76.5 (they should be .500 in that division - the Angels are overrated, and the other two clubs are hit and miss)
Diamondbacks under 75.5 (they should get to 90 losses quite easily)
Blue Jays over 69.5 (jump all over this one, too - this team is sadly underrated, nowhere near a 95-loss team)
