If JAX loses they are still leading the division.
The Colts hold an inside edge on the other AFC Wildcard teams because of their 6-3 conference record.
If the Bills lose one and Colts win 2, as a Wildcard team they still are above the Bills.
If the Jags win 2 they win the division.
Jags losing today gives Bills a better chance. If either loses a game the Bills are above them.
