Thankfully, Urban Meyer is off the hook again, as he has Zach Smith - an impeccably trustworthy source - claiming he never told Urban about his 2013 DUI/OVI arrest.
Basically, Urban knew in 2009, but did the right thing in trying to help a young troubled couple; did not know about 2013; knew about 2015 but followed reporting protocols; and then knew about 2018 after someone wrote a story about it, and only then fired Smith.
In my opinion, there are only two possible explanations and conclusions for all of this: 1. Urban Meyer is a thoroughly incompetent manager, and should be fired; 2. Urban Meyer is a thoroughly corrupt manager, and should be fired.
