I understand the Jerry dilemma, and yes, overall blame for the past near 30 decades is on him, but the thing is he ain't going anywhere and his family will own it for the lifetimes of many on this board. So people either have to deal with that or find a new team. I've come to grips with it and washed it down with a shot of apathy and a chaser of cynicism.
And yes, teams do win with less. Do you really think all the Super Bowls or even NFC/AFCCG of the past 30 years were won by perfectly built rosters? Burrow hasn't had an offensive lineman so much as get in somebody's way his whole career. Mahommes literally has a TE to throw to and a RBBC that rarely does anything. Rams loaded up and won one and then went to cap hell. Bucs went and got Brady to cover up their deficiencies and that worked for a year. Those are just some I can think of recently.
