The next head coach is inheriting a mess

LOL I really don't think people know how little Campbell had to do with turning the Lions around. He truly is the Ed Ogeron of the NFL His best move was to elevate Johnson to OC and hire Glenn as DC. Other than that it's pretty much all their GM Holmes was the architect
from 2020 to 2024 the Lions from the Stafford trade and their own picks had 19 draft picks in the top 100 of the draft AND they got Goff. With that kind of draft capital it's pretty hard to not be in a position to excel. Also they had plenty of cap space.
People also forget that Goff stunk up the joint until Johnson was made OC
Yes Campbell gets his players to play hard , just like Ogeron did at LSU
But he did not build that team , Holmes did and it's Johnson that runs the O and Glenn that runs the D
If the Saints had Holmes as GM and that kind of draft capital and cap space even DA would be successful

The turning around of the Lions has been a real team effort. From the owner hiring Chris Speilman to be in charge of building team culture. To the job Holmes has done. To what Dan and his staff has done on the field.

Dan does not get enough credit. I once had a martial arts instructor who had a degree in sports psychology and the man was amazing at motivating and getting people to buy in. He only did some of the intruction, but he organised the curriculum, was there to guide the instructors, provided direction, and was a constant source of evaluation and motivation. Dan reminds me of that guy, who had probably the most successful martial arts dojo in my country.
