The Bank of America is one of my favorites in Jax. The Heard Building was nice, and it's a shame that they tore it down, but lets move on for godsakes; Just my opinion feel free to disagree, I just think that the Heard (and other old buildings alike; Robert Mayer etc etc) talk is extremely 'stuck in the past' redundant. There are many 'Heard stories' are around America, and no one else (other cities) seem to use that as some kinda crutch against humanity or something.
IMO Helmut Jahn is a decent architect. I agree that his work isn't known to 'blow people away' as he doesn't seem to have many of these 'best of' awards, but I've seen alot of 'best of' architecture that looks hideous; Just because something is supported with a minimal amount of pilings, or is a 'twisted tower' doesn't necessarily mean that it should win a award. I guess that beauty is in the eye of the beholder, as they say.
