All the Brady "hate" mentioned above is considered legit out here in Indy, where I live.
It's his amoral "image" that is despised:
- Belichick cheating flunky - rule breaker
- Supermodel wife - brazen life of excess
- Out-of-wedlock spawn merchant - immoral
- Metrosexual pitch man - materialistic
(Plus he's considered a frequent on-field trash talker, which tends to rile up opponents [see Sherman, Richard].)
There is never any comment about his profession, per se, unless it is some attempt to discredit his relative dominance over Peyton's teams.
By all accounts Manning is a very good guy to Joe Public (this college era story is just "youth being wasted on the young", imo). His SOTY article further amplified his positive qualities. However, I would say there are an equal number of non-malicious stories regarding "the real Manning" out here that are conveniently (and probably rightly) ignored in these here parts.
(P.S. I'm a Michigan grad as well, and I hadn't heard that TB12 was big-timing ex-teammates, but it only seems a bit natural that he travels in different circles now, which may create some backlash. FWIW, on the invitation of Brady Hoke, he did visit the football team during the bye week this year and gave an impassioned speech to the team in support of their efforts and the need to embrace the experience of being a member of the football team.)
