Not to beat this horse too much, but Mac was way worse. Idzik had a plan at least, he just couldn't draft and got fired quickly. Mac couldn't draft, had no idea how to build a team, sweet talked the owners into letting him stay on and destroy the team further, and got us Gase. There's a reason Idzik is still employed in the NFL, whereas Mac is unemployable at any level of football.
Those dummies in Seattle gave up 2 1's and then sign box boy to a ginormous contract? They will regret it.
