Good stuff BUT....
Chargers played in a much tougher AFC West vs, *TEXANS limping in the weak-arsed AFC South....
Chargers played Chiefs, Broncos and Raiders twice. *TEXANS played Colts, Jax & Titans twice. Yes, Bolts beat Broncos twice, quite a feat unto itself, but the *TEXANS beat Colts twice.
Yes. *TEXANS' D might be better as you say, but today's NFL it is the Offense that is the driving force...and the Bolts clearly have the better O.
Enjoy the game,
