Saints fired OC Pete Carmichael

Bills or 49ers who have more physicality built into the offense. Miami went the speed version of the 49ers and it's a good fair weather/dome offense that doesn't do well later in the season and in the playoffs.

Miami went with 4.2/4.3 guys without much strength/power. Give me 4.4 guys who are a stronger and more powerful, so pretty much the middle ground between the 49ers and Dolphins which would be very close to the 49ers.

I also like how Buffalo uses 2 TEs. It takes some of the beating off of their smaller WRs. We have 2 small WRs who need to be protected.
The 49ers (Shanahan) coaching tree would be my pick, I like their physical running game and creativity in the passing game.
