That looks about right, since 2012
Record against losing teams (-.499): 11 - 9 / .550
Record against awful teams (-.250): 6 - 4 / .600
Barely :500 against shitty teams they should have dominated. Where the blame lies for that, I don't know. Mainly against the roster, I suspect.
Unfortunately 5 W and 5Ls against teams with a winning % under .500 and above .250 doesn't get you to playoffs; same with a 6-4 record against the bottom teams.
I'd also love to see margin of victory considered; not because it matters but often those 3 point wins against teams like the lowly titans have the feel of a loss, often influencing our perception.
