A dominant win is winning by a LOT, and having overwhelmingly better stats. The Chiefs had neither...
Good lord even just Google the definition of a dominant win and educate yourself. This isn't a hill you wanna die on, even though you're fighting for your life to do so.
No, a dominant win is *NOT* winning by a lot, that's a blowout. Quit backpedaling from your misread/misunderstanding.
A dominant game is a game where you're in control. The Chiefs spending the entire second half of the game against the Lions never giving them a chance to possess the ball to take the lead, was dominant.
Per Merriam Webster: "a: commanding, controlling, or prevailing over all others"
That's exactly what I just said about the Chiefs win over the Lions.

Seems this isn't a hill you want to die on. And FWIW, you never want to battle me over terminology, technicality, or otherwise, I will firmly
*DOMINATE* you.
