As much as I hope, I doubt it happens. LaFleur likes the guy, or he wouldn't have let him hang around this long. I don't think he is gonna show him up/embarrass his worthless ass by firing him now. Besides, he'd have to answer a lot of questions about why the hell he waited this long. More likely, he will "retire" gracefully after the season.
Bring on a young smart DC to replace him, maybe Al Harris, and change the damned Barry scheme.
