When have Docker's ever been ever been considered "horrible dad pants"? They have been a top "business casual" choice every since I can remember.
Back when I had to get dressed for work, Dockers and a polo shirt, or Dockers and a button-up dress shirt were always my go-to office garb.
I am the opinion that proper attire for a head coach is a hooded sweatshirt with the sleeves cut off.
(But I may be biased.)
Nothing but respect for the Hooded Wizard of the North, but since Harbaugh is the only HC in the NFL with a better career winning percentage than Belichick, maybe the Wizard should tuck that ratty-ass hooded sweatshirt in.
