Honestly tho, if miami doesn't get no 1 seed, jax would be the least of an issue imo compared to chiefs or ravens being no 1 seed. That's why it's hard for me to root for ravens winning because if miami can't get no 1 seed, I'd rather jax get it than chiefs or ravens. The challenge playing away is not just the teams, but home fans and weather conditions. Baltimore and kc can be cold and/or snowy. Jacksonville is in florida so not a weather advantage for jaguars vs miami.
If there's a "home away" game for miami, you couldn't have one more than this. I don't think jag fans are die hard either with a 90s expansion team and in duvall. I could definitely see a ton of miami fans filling out that stadium too. So weather plus fan base. So for me, if miami can't get no 1, I think number 2 seed is huge as it sets up miami to have home field for playoffs should no 1 seed be upset in playoffs. If jags had no 1 and miami no 2. Miami would have 2 home games if miami wins wc. And florida weather as explained if jags get no 1 and miami plays them conference championship or if jags get upset then that team plays at miami
