I think McVay made huge mistake by not going for it on that last drive. It was 4th and 1/2 yard to get 7 pts to up 4. Instead, they settle for FG to tie it up and Saints get good field position on their next drive. Basically, If Im Rams, I much rather be down 3 giving the Saints the ball on their own 1, than tied giving the saints the ball on their 30.
