Getting your boss fired makes future bosses want you less, especially when you're even more powerful on this level. (Also unclear about the quality of the job he's done or affinity for recruiting)
he's done... ok. a ton of bama fans, myself included, aren't very happy with him (and marone). our oline has been really poor, especially the right side, and i don't mean just by bama standards. we are 111th in tfl allowed, 108th in sacks, 77th in rush offense (83rd in rush yr/attempt, so not really a volume stat either). good thing we have a heisman level qb, cause the passing game is only thing keeping our offense moving and scoring.
and while bob deserves some credit for keeping it moving only way we can, he's also not been great at overcoming when we've struggled even there. like the auburn/lsu games. they were just pinning ears back and rushing us hard. but we didn't call any plays to stop that. no screens, draws, quick slants/pass routes, flairs, etc. anything to catch the d too far up field.
i fully expected our offense to take a step back this year. but there is no reason for our oline to be that weak. it's not like they're young either. 1 sr, 3 jr and 1 so. there was 1 injury right before season, but it should be solved by now with the talent we have.
to his defense, he (and marone) came in a had to learn our offense, not other way around. that's how saban does it. this is the bama offense/defense, and you'll learn it and run it with your own style/flair, but we don't implement your offense. so being first season, he might have had a learning curve to overcome. but it's been a full season and seems to be getting worse as it goes on.
as far as recruiting, he's ok. it's hard to tell. he's only credited with 2 recruits, but they're both highly rated (5* qb, 4* te). not much sample size, but what's there is really good.
imo, he' still a good coach. too much history says he is. but he isn't a good fit at bama for whatever reason.
