A trio of Power 5 football coaches have already lost their jobs and the calendar hasn't hit October.

With Scott Frost (Nebraska), Herm Edwards (Arizona State) and Geoff Collins (Georgia Tech) handed their pink slips -- or "mutually parting ways" with their schools -- who is next in line?

The day after Collins was fired, SportsBetting.ag opened the market on Tuesday with Colorado's Karl Dorrell and Auburn's Bryan Harsin the co-favorites at 200. The public quickly jumped on Harsin, pushing the embattled Tigers coach to 100 within a few hours.

Harsin kept his job following an inquiry over the offseason, but the critics have remained loud despite the Tigers' 3-1 start. Auburn eased into the season with wins over a pair of non-Power 5 teams before a blowout loss to Penn State and a narrow overtime win over Missouri -- all at home.

Colorado's 0-4 start has been much rougher with the Buffaloes being outscored a combined 173-47. Dorrell, who went 35-27 in five seasons at UCLA, is now 8-14 in his third season in Boulder.

The third-shortest odds belong to Stanford's David Shaw. He opened at 300 on Tuesday but those odds lengthened to 500 despite the Cardinal coming off another decisive loss to Washington.
