Well no team in the AFC has the elite WRs to match what the Rams just did except maybe the Bengals.
While there is plenty of blame to go around let's not forget that Nacua and Kupp both made a couple circus catches. Stafford didn't throw his usual once a game lame duck interception.
In order for the Rams to beat the Bills: Their Offense had to play their best game in years, shotty officiating, Allen missing a couple wide open throws and questionable decision making from the coaches. That was just to win by 2. If the Bills make it to the Superbowl this year it will because of their unstoppable offense rather than the crappy McDermott Defense we always see
