Atlanta's pass rush doesn't hold a candle to Buffalo's. I don't think they could execute that game plan and win with the same personnel.
Plus, McVay is not known to be a stubborn coach, and doesn't just bash his head into a wall again and again when something fails. Pretty sure there's going to be a discussion during the next 9 days about how to block better, and to get Stafford to target a WR not named Kupp. (He targeted Kupp 15 times, and all his other WRs combined saw just 10 targets.)
I don't think any of us will put the Rams in crisis mode for losing to another team picked as a Super Bowl contender by 3 TDs. One game sample size, and all that. We'll see if the sports media has "overreaction takes" on the morning shows or not.
