Except for ARZ they were winning close games.
Yes, and what I noticed re-watching them is that the Rams had the upper hand in the Bucs and 9ers games, but mistakes made those games closer than they should have been. The Bucs game took a parade of errors (2 Cam fumbles, a Kupp fumble, and a missed snap, all recovered by TB) to get them back into it. In the SF game, the Rams were dominating the ball, drove the length of the field, and had a deflected pass INT in the end zone. That was tighter than the Bucs game (which was really a blowout).
The Super Bowl had the famous OPI that got CIN their only 2nd half play, and the Rams were without Woods, OBJ, Higbee, Mundt, and Blanton, and Akers was not 100%. They had Stafford and Kupp left.
I think SF was the only team that really played them close. The other 2 games were close because of inexplicable flukes and injuries.
