This is a great article, and this experience will prove to have been invaluable for McVay's future. He exorcised the ghost of his previous Super Bowl appearance where he failed to adapt and came up with a great counterpunch precisely when it was needed most. He's obviously not going to forget this experience, and in future games where things go sideways, where the Rams get bogged down, he'll call on this experience and make the necessary adjustments to win the game.
Simply put, this drive was the point where McVay went from being a very good coach to an elite coach. Very good coaches can design and offense, a scheme, a gameplan that looks great when things are going your way. The elite ones can adapt, in the biggest moments, when your scheme and your gameplan are stymied by the opposing defense.
This drive gave the Rams more than just a Super Bowl win. With McVay drawing on this experience, it will give the Rams more wins down the road when we inevitably run into some adversity.
