Rams did this one year in 2018 and went to the SB that year...
The next year everything collapsed because the entire offense was built around Gurley destroying teams and his knees couldn't hold up.
In 2020 they revamped alot of that roster and brought in Ramsey. They ended up with the #1 defense in the league, but the offense still was ass because of Goff.
This year they revamped the offense, to fix the problems they had last year.
I actually love this approach. They aren't content with just being a playoff team like Seattle, Green Bay, Baltimore.....they really want to win and are going all out.
