Haha! I can see how it might feel that way! But after losing Cooper Kupp for multiple playoff runs now, I am strongly in the camp of, if there does not appear be anything huge to gain from winning our last game of the year, send out the backups, and play to win, but if we lose, so be it. The health of the stars has to be the top priority. It truly is about health for me. Football is a super physical game. The potential for injury is too high. I suspect McVay might feel similar. He won't play starts in pre-season. And recall, that was not always a common move. McVay was the first to implement it to such a great extent. Now, nobody plays starters in pre-season.
A few years ago, I would have agreed with your position, for all the reasons you eloquently stated in both posts. (And for the record I agree with resting starters in preseason).
But this board had some interesting debates on this topic in 2017. McVay did what was thought to be the smart play, and rested most of the starters vs. SF in the last game. (And yeah, McVay did the obligatory pep talks about how "the backups will be expected to get the W." )
Well, the Rams backups got crushed. And then in the next playoff game against ATL, the Rams had a sluggish and sloppy first half and went on to lose. A lot of fans and pundits blamed the ATL loss on the decision to rest starters vs SF.
A key part for me in the debate is hearing that Belichick is very much against resting starters before playoffs. Belichik talked about how important it was to keep winning momentum, and to send a consistent message to the team that 100% commitment is required every single game for a winning culture.
Anyway, it's a real interesting debate with strong arguments on both sides. I've switched my thinking on this one. As much as I hate the cheater Belichick, I also think he's a genius and the best coach in football. Belichick has a proven record of playing starters in meaningless games at the end of the season-- -- even at risk of injury-- in order to keep the winning momentum for the playoffs.
