We've got 3 games of really subpar to abjectly shitty QB play after which Arch is mopey and says, "I played poorly. I've got to play better."
It doesn't take much of that for people to lose faith. And by people, I don't mean fans who are always going to be ignorantly fickle. I mean coaches and teammates. And if a head coach insists on testing the definition of insanity by trotting the same non-performing player out there as a starter without seeing if someone else can be more than shitty on Saturdays, well, it doesn't take much of that for players, other coaches, recruits and those fickle fans to lose faith in the head coach, too.
Compare Arch's postgame demeanor and subsequent performance after subpar/shitty play in these 3 games to this guy's. If this is an example of the intangible "it" that the best players have, Arch right now is a void of "it". I wish it was different for him.
