I have a hard time believing Loomis would fire him after 1 year. We had two years of Dennis Allen who was quite literally one of the worst head coaches in history of NFL and Loomis was defending him tooth and nail after year two, and seemed like he was prepared to do the same after year 3 had the owner not stepped in (and to some degree, still did defend him).
I doesn't matter who we take, I think they'll be here for at least 3 years bare minimum even if we go 0-17 in year 1 or 2.
