it's not hard to figure out who you play...
You play your division twice.
For Example:
The Steelers play:
@Baltimore, vs Baltimore
@Cincinnati, vs Cincinnati
@Cleveland, vs Cleveland
Then you play a division in the opposing Conference.
The Steelers play the NFC East:
Philadelphia, New York, Washington, Dallas
Then you play a division inside your conference(not including your own).
The Steelers play the AFC South:
Indianapolis, Jacksonville, Houston, Tennessee
Finally you play teams that finished in the same position you did in your own conference:
The Steelers play:
New England and San Diego (They already play Indy so that team isn't included on this list)
