I haven't been part of this discussion at all, and I'm not at all a "fan" of Huntley. But, I think he has far surpassed my own expectations on him. To me, he's been better passer than RG3 was for us the last few years, which OTOH isn't saying much. He's got a bunch of bad things going for him, but I've been impressed with the way he runs the offense; doesn't seem to be confused by scheme and doesn't look rattled. The stats, although not great, are not terrible either.
Probably correct that he's a career backup, but I don't think many people though Tyrod was going to be the starting QB on 5(?) different teams when he left here. Multiple of those being teams he was the week 1 starter. So perhaps Huntley can develop into something like that? Perhaps not, but I'm at least fine with what he's giving us at the moment.
