Even CIN lost tonight, HOU lost and IND win next week, HOU is in

Because they only need one of the followings to happen next week:

CIN win,  or NYJ win, or NO win, or DEN loss,  or MIA loss, or KC win + PIT loss

In short, the chance that HOU is out = 1- the chance that IND is in, which is roughly equals to 1.
