McCarthy will be fine....I was told you can't fire a HC in his first year with the team (unless your name is Steve Wilks, to which i was told he doesn't count).
Or any of these other guys:
Chip Kelly, 49ers, 2016, 2-14
Jim Tomsula, 49ers, 2015, 5-11
Mike Mularkey, Jaguars, 2012, 2-14
Hue Jackson, Raiders, 2011, 8-8
Jim Mora, Seahawks, 2009, 4-12
Cam Cameron, Dolphins, 2007, 1-15
Art Shell, Raiders, 2006, 2-14
Marty Shottenheimer, Redskins, 2001, 8-8
Al Groh, Jets, 2000, 9-7
