If not for the whole Aaron Hernandez thing, I'd debate the whole "Urban is a POS" thing. It think, at best for him, he has a weird and misplaced sense of loyalty to people who are clearly bad people.
With Zach, the loyalty is to Earle Bruce who was fired at least in part due to his own mental instability and grudges he held against others. What has been clear looking at the rest of the Smith clan via Twitter last night (Zach and brother Colin T., in particular) is that Zach's behavior is not a one off. This is pretty much how the Smith clan rolls. I thought I had determined through my internet research that Colin T. is a young lawyer with a firm in Dayton, OH. But I couldn't confirm that. If I could confirm that, I was going to suggest that he not follow his brother's lead and spread rumors and other defamatory statements on Twitter to avoid not only being sued but so that he could have a successful legal career.
Urban covered up for Zach so many times and brought him along with him from UF to tOSU (back home--family reunion). It would be interesting to see what debts Urban feels he owes the Bruce family other than his outsized sense of loyalty.
