The Threat Level started in 2017.
I know! I was surprised too, but I looked up the very first iteration of this here internet blog and it's true; Threat Level: Michigan was christened with a nod to a sitcom that had only been off the air for a mere four years (and, uh, like... 12 years since the original joke in said sitcom) by the time I decided that referential humor never, ever gets stale.
Anyway, the year before, in 2016, the Wolverines had begun their season a pretty incredibly impressive 9-0. This included a yes-I-checked-this-five-times-to-be-sure 78-0 win against Rutgers and a 59-3 victory against Maryland, but unless you're one of the handful of Michigan fans who hate read this thing every week to satisfy the customary persecution complex that goes along with life in the Big Ten, you can't even tell me who Michigan's starting quarterback was that year.
