I used Tomlin and Belichick as earlier examples - guys who grind through the peaks and valleys over the years no matter what.
You brought up Sean Payton, so let's briefly compare McVay to Payton. Although Payton did enjoy 15 good years with the Saints, he also didn't put a gun to the owner's head and demand they trade an infinite number of picks for...Matthew Stafford, who may not even be their starter next season.
Don't forget, Goff got the Rams to the SB and won a game with a broken thumb when he shouldn't have even been on the field...yet McVay laid all the blame on Goff and ran him out of town. So much for taking responsibility - typical millennial! So the Rams did what Millennial McVay demanded (otherwise, the soft crybaby may have even walked back then) and now look at them. Probably will have to trade some of their core players just to recoup some of that draft capital. Either way, they're going to suck for a while.
Now comes the word Millennial McVay is said to not want to accept the "hard work" that goes into a rebuild - a rebuild HE is responsible for! After all, there's nothing to rebuild, the cupboard is empty - no picks! He just wants to slide into another cozy position with a contender - all the glitz and glamor without the hard work that goes into building a winner.
That's how I see it..
