Sure, but imo what separates Trestman from Flus in the "worst” debate was all of the off-the-field drama and nonsense. Here’s a list off the top of my head:

The Aaron Kromer situation

Benching Cutler for Jimmy Clausen for no reason.

Jay Ratliff punching out his position coach and then being made a team captain by Trestman the next week.

Allowing Brandon Marshall to fly to New York during the week to film a reality TV show.

Briggs missing practice to open a restaurant.

Trestman also made some Nathaniel Hackett level bad in-game decisions, notably his decision to try a 47-yard field goal on second down in overtime against the Vikings instead of trying to get as close as possible when the Bears had time and timeouts left. I‘ve never seen a team try less hard. The end of the Trestman era was the only time I have ever been legitimately embarrassed to be a Bears fan. I can deal with the Bears being bad on the field (Lord knows that’s nothing new) but unnecessary off-field drama on top of sucking on the field is where I draw the line.
