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.
And, for Tomlin's tenure:
Record against awful teams (-.250): 21 - 6 / .778
Flirting with 80%. Not terrible...not awesome either, but nowhere near as bad as its been portrayed. I think I'll give that article its own thread later. Worthwhile information, IMO.
