Me too. I love 'em vs CLE in wk15 and IND in wk16. But OP had focused on wk14 and it's that wk14 date at Heinz field that gives me some cause for pause.
Some available defenses vs leaky offenses in my league for wk 14 are:
DEN (who hasn't been scoring that much) gets NYJ at home.
BUF (who's been scoring even less) gets IND at home
HOU (with meh scoring) gets SF at home
Some available tough defenses vs stingy offenses for wk14 are:
MIN (w meh scoring lately) travels to CAR
PHI (hot) travels to LAR (who surprisingly is 30th in points allowed to defenses)
SEA (cooling off lately n missing key pieces) travels to JAX (Bortles, right ? But only 23rd in points allowed this year)
For me, it might pay to hold off a week or two to get a clearer picture of DEF scoring and OFF yielding trends before selecting a companion DEF to carry along with BAL.
