Maybe some are "defending" Loomis but many are just clarifying the fact of the situation. Problem is that we have reached the point on this board that if your post doesn't include a rant about how Loomis needs to be fired, you are considered to somehow be complicit in the downfall of the team and should be ostracized from Saints fandom.
But, there is information out there that while Loomis did not want to fire DA mid-season, he did ultimately agree with Mrs. Benson that it had to be done when it was done. Was it reluctant agreement based on not really having a choice? Probably so. And in the end this was likely more of a business decision by Mrs. Benson to placate the fan base and hope it would help season ticket sales. Or at least that they wouldn't lose as many as they would if they waited to fire DA until the end of the year.
But I also didn't expect Loomis to call DA in and tell him to get the fork out of here your loser arse is fired. It's not Loomis' style nor is it the Saints' style. So, even if he ultimately agreed with the decision, he wasn't going to be a dick to DA and he was going to put it as softly as possible. Which kind of matches with DA saying that Loomis "wasn't really in favor of the decision".
Beyond that Underhill and Tripp have reported that Loomis likely was going to fire DA at the end of the season but he has a philosophy that you don't fire coaches in the middle of a season because it doesn't result in more wins and you look bad as an organization. And, frankly, there is some sense to it since perspective coaches will like the idea that they get time to develop the team and try to prove they can turn things around. Tom Benson had the same philosophy and it's why Mora ended up quitting mid-season before Benson would fire him.
Also, had we kept DA for the entire season, we likely lose at least two more games and end up with a top 5 pick so maybe keeping him for the rest of the season would have been the strategic move? But, I will admit that I was just tired of seeing and hearing DA and wanted him gone by mid-season since it was clear it was not going to work.
And honestly, I think the bigger criticism of Loomis is that he didn't fire him after last season and allowed him to coach this year. And, I personally think he should have realized it wasn't working after the first year and DA should have been let go then.
