From 2018 until he was dismissed back in November, Patricia's record with the Lions was a disappointing 13-29-1.
Patricia's defense never gained a foothold in Detroit, and his bend-but-don't-break philosophy was ineffective from the moment he stepped foot in Motown.
"It was a hard decision, because they are both terrific people and worked very hard and tirelessly for this organization," Lions principal owner Sheila Ford Hamp said after Patricia's dismissal. "It just clearly wasn't working. It wasn't what we had hoped for when we hired them, and so I don't know if there was an exact moment."
Brown, 65, whose defense in 2020 was a sore spot due to the opposition easily picking it apart, became expendable, following a subpar season for the Wolverines.
According to Brandon Brown of SI Wolverine Digest, "It became very clear that other staffs figured Brown out. Throw in just how bad U-M's defense looked against Ohio State over the last three years, and it's been enough for a while."
Whose defense performed worse in 2020: Matt Patricia's or Don Brown's?
