I'm not saying Miles and Cameron don't deserve to be fired. Les has greatly under-achieved his recruiting. Cam Cameron has been abysmal developing QBs. And the clock management on that last drive looked like pee-wee league.
But what do they gain by doing it now? They throw in the towel on the season, trash any hope of a dignified ending (I know, I know...dignity is in short supply in Baton Rouge on the best days), trash the seniors' season and Fournette's swan song, and for what?
Firing Miles and Cameron now would be a childish temper tantrum in response to a disappointing loss. Yeah, it might feel good in the moment, but the next 60-90 days are really gonna be difficult, and you have no idea what's on the other end of it.
Wait until the week of the last regular-season game, announce that there will be a change at the end of the season, and give it at least some semblance of consideration and order.
